Qualcomm ARM64 defconfig updates for v6.9
Enable the Qualcomm PBS driver to resolve the dependency from the Light
Pulse Generator (LED-driver) on modern Qualcomm platforms. Enable the
X1E multimedia clock controllers, to provide clocks for the various
multimedia blocks. Enable Global clock controller and interconnect
drivers for the QDU1000/QRU1000 platforms.
Enable the audio drivers and the Goodi Berlin touchscreen driver, used
on SM8650 QRD.
Enable the MAX20411 regulator driver drive the GPU rail on SA8295P.
Lastly mark the Qualcomm interconnect providers that feeds UART
instances as builtin, to ensure the console exists when userspace is
launched.

ext4 filesystem can mount ext2, so drop CONFIG_EXT2_FS to make builds a
bit faster. Drop also redundant CONFIG_EXT3_FS, because it just
selectes EXT4_FS.

With interconnect providers built as modules Qualcomm SM8250 and QCM2290
platforms launches init without /dev/console being backed by the debug
UART.
Build there drivers into the kernel, to make sure the dependencies for
the UART driver are available and thereby give userspace access to the
UART without having to re-open the console, once the deferred UART
driver has probed.

Commit 72fee6b0a3a4 ("fbdev: Restrict FB_SH_MOBILE_LCDC to SuperH")
disabled availablity of the SH_MOBILE_LCDC driver on the RENESAS arch.
This innocent change has a significant side-effect on the ARM's
multi_v7_defconfig, because FB_BACKLIGHT symbol is no longer selected,
what in turn leaves BACKLIGHT_CLASS_DEVICE symbol selected only as
a module. The latter disables some backlight related code in the DRM
core, because the DRM core is set to be compiled-in in this defconfig.
This leaves all DRM display panels without integrated backlight control,
even if the needed modules have been properly loaded and probed.
Fix this by selecting BACKLIGHT_CLASS_DEVICE to be compiled-in in
multi_v7_defconfig.

The Keystone platforms used their own keystone_defconfig mostly to
enable CONFIG_ARM_LPAE which could not be added to the multi_v7 config.
Now that we have multi_v7_lpae_defconfig/lpae.config target we can and
should use that defconfig for Keystone. Add the remaining must-have
options for Keystone support to multi_v7_defconfig.

Pull more bcachefs updates from Kent Overstreet:
"Some fixes, Some refactoring, some minor features:
- Assorted prep work for disk space accounting rewrite
- BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
makes our trigger context more explicit
- A few fixes to avoid excessive transaction restarts on
multithreaded workloads: fstests (in addition to ktest tests) are
now checking slowpath counters, and that's shaking out a few bugs
- Assorted tracepoint improvements
- Starting to break up bcachefs_format.h and move on disk types so
they're with the code they belong to; this will make room to start
documenting the on disk format better.
- A few minor fixes"

bcachefs btree nodes are big - typically 256k - and btree roots are
pinned in memory. As we're now up to 18 btrees, we now have significant
memory overhead in mostly empty btree roots.
And in the future we're going to start enforcing that certain btree node
boundaries exist, to solve lock contention issues - analagous to XFS's
AGIs.
Thus, we need to start allocating smaller btree node buffers when we
can. This patch changes code that refers to the filesystem constant
c->opts.btree_node_size to refer to the btree node buffer size -
btree_buf_bytes() - where appropriate.

======================================================
In __bch2_ioctl_subvolume_create(), we grab s_umount unconditionally
and unlock it at the end of the function. There is a comment
"why do we need this lock?" about the lock coming from
commit 42d237320e98 ("bcachefs: Snapshot creation, deletion")
The reason is that __bch2_ioctl_subvolume_create() calls
sync_inodes_sb() which enforce locked s_umount to writeback all dirty
nodes before doing snapshot works.
Fix it by read locking s_umount for snapshotting only and unlocking
s_umount after sync_inodes_sb().

bch_fs::snapshots is allocated by kvzalloc in __snapshot_t_mut.
It should be freed by kvfree not kfree.
Or umount will triger:

The variable tmp is being assigned a value but it isn't being
read afterwards. The assignment is redundant and so tmp can be
removed.
Cleans up clang scan build warning:
warning: Although the value stored to 'ret' is used in the enclosing
expression, the value is never actually read from 'ret'

drop_locks_do() should not be used in a fastpath without first trying
the do in nonblocking mode - the unlock and relock will cause excessive
transaction restarts and potentially livelocking with other threads that
are contending for the same locks.

Factor out bch2_journal_bufs_to_text(), and use it in the
journal_entry_full() tracepoint; when we can't get a journal reservation
we need to know the outstanding journal entry sizes to know if the
problem is due to excessive flushing.
