The arch_timer_evtstrm_enable hooks in arm and arm64 are substantially
similar, the only difference being a CONFIG_COMPAT-conditional section
which is relevant only for arm64. Copy the arm64 version to the
driver, removing the arch-specific hooks.

The only difference between arm and arm64's implementations of
arch_counter_set_user_access is that 32-bit ARM does not enable user
access to the virtual counter. We want to enable this access for the
32-bit ARM VDSO, so copy the arm64 version to the driver itself, and
remove the arch-specific implementations.

The arm and arm64 VDSOs need CP15 access to the architected counter.
If this is unavailable (which is allowed by ARM v7), indicate this by
changing the clocksource name to "arch_mem_counter" before registering
the clocksource.

According to HW spec, we have to disable the counter before setting
it, if we don't this, in pressure test, sometimes the timer might
not generate interrupt any more.
And this patch also fixes a typo for register set by changing 0x7
to 0x3. 0x7 is loop mode in HW, but here we are using oneshot 0x3.

Currently we wait until both cp15 and mem timers are probed if we
have both timer device nodes present in the device tree without
checking if the device is actually available. If one of the timer
device node present is disabled, the system locks up on the boot
as no timer gets registered.
This patch adds the check for the availability of the timer device
so that unavailable timers are discarded correctly. It also adds
the missing of_node_put.

/*MCF_IRQ_EINT1*/ { .icr = MCFSIM_ICR1, .index = 28, .ack = 1, },
...
The problem stems from the changes to make all ColdFire register addresses
absolute, in commit d72a5abb ("make remaining ColdFire 5272 register
definitions absolute"). That change did not take into account that the
addresses were stored as offsets in the irqmap of the intc-5272.c code.

This "type" seems to be an extra hint for m25p80 about the flash. Some
archs register flash_platform_data with "name" set to "m25p80" and then
with a real flash name set in "type". It seems to be a trick specific
to the m25p80 so let's move it out of spi-nor.
Btw switch to the spi_nor_match_id instead of iterating spi_nor_ids.

Current situation with 4K sectors is quite messy. First of all, some
MTD "users" don't work with such small size. An example may be UBIFS
which requires 15 KiB erase blocks as a minimum. In theory spi-nor
should provide multiple erase regions and MTD "users" should use the
one they need. Unforunately that is not implemented.
In the result our flashes database in spi-nor is hackish. For some
flashes we pretend they don't support 4K sectors just because some
distribution uses UBIFS on it. This ofc leads to conflicts, like
Samsung using w25q128 with 4K sectors vs. OpenWrt requiring it to
pretend it's 64 KiB blocks only.
My idea (plan?) for fixing this situation:
1) Use real hw info (this requires a way for disabling 4K for now)
2) Provide detailed info about erase regions
3) Make UBIFS work with devices that support 4K sectors
