All of the config data files and all of the register definition
files (plus a few others) use GSI_EE_AP, which is defined in
"ipa_version.h". Include that header where it's needed.
All of the IPA register definition files include "../ipa.h", though
none of them need anything defined there. Similarly, all of the GSI
register definition files include "../gsi.h", but don't need anything
defined there. Remove these unnneded includes.
All of the configuration data files include "../gsi.h", though none
of them need anything defined there, so remove these includes.
Remove other includes of local header files that are not required.

Some IPA header files use types defined in <linux/types.h>, but do
not include that file:
- In "ipa_mem.h", the ipa_mem structure has u16 and u32 fields
- In "ipa_power.h", ipa_power_retention() takes a bool argument,
and ipa_core_clock_rate() returns u32
- In "ipa_version.h", ipa_version_supported() returns bool
Include it in these files to satisfy their dependencies.
The ipa_qmi structure (defined in "ipa_qmi.h") contains a work
structure, so include <linux/workqueue.h> in there.
All of the data and register definition files, as well as "reg.h",
use the ARRAY_SIZE() macro. Include <linux/array_size.h> everywhere
it's used.
Similarly, all register definition files (and a few others) use the
GENMASK() macro, so include <linux/bits.h> to ensure it's defined
where used. BIT() becomes available by including this file also.

Now that we explicitly define each register field width there is no
need to have a special encoding function for the event ring length.
Add a field for this to the EV_CH_E_CNTXT_1 GSI register, and use it
in place of ev_ch_e_cntxt_1_length_encode() (which can be removed).

Starting at IPA v4.5, almost all GSI registers had their offsets
changed by a fixed amount (shifted downward by 0xd000). Rather than
defining offsets for all those registers dependent on version, an
adjustment was applied for most register accesses. This was
implemented in commit cdeee49f3ef7f ("net: ipa: adjust GSI register
addresses"). It was later modified to be a bit more obvious about
the adjusment, in commit 571b1e7e58ad3 ("net: ipa: use a separate
pointer for adjusted GSI memory").
We now are able to define every GSI register with its own offset, so
there's no need to implement this special adjustment.
So get rid of the "virt_raw" pointer, and just maintain "virt" as
the (non-adjusted) base address of I/O mapped GSI register memory.
Redefine the offsets of all GSI registers (other than the INTER_EE
ones, which were not subject to the adjustment) for IPA v4.5+,
subtracting 0xd000 from their defined offsets instead.
Move the ERROR_LOG and ERROR_LOG_CLR definitions further down in the
register definition files so all registers are defined in order of
their offset.

Define field IDs for the remaining GSI registers, and populate the
register definition files accordingly. Use the reg_*() functions to
access field values for those regiters, and get rid of the previous
field definition constants.

The next patch adds a GSI register field that is only valid starting
at IPA v4.11. Create "gsi_v4.11.c" from "gsi_v4.9.c", changing only
the name of the public regs structure it defines.
