Do not apply bitwise AND to register value and expected value, only
apply bitwise AND to register value and mask, and only then compare
the result with expected value that the function polls for.

Prepare v2024.07-rc5

Make sure the OS would not get any spurious IWDG pretimeout IRQ
right after the system wakes up. This may happen in case the SoC
got woken up by another source than the IWDG pretimeout and the
pretimeout IRQ arrived immediately afterward, but too late to be
handled by the suspend main loop. In case either of the IWDG is
enabled, ping it first and then return to the OS.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Remove <common.h> from all mach-stm32 and mach-stm32mp files and when
needed add missing include files directly.

In case the system has resumed successfully, the PSCI suspend resume
code has to jump to the 'ep' successful resume entry point code path,
otherwise the code has to jump to content of the LR register, which
points to failed resume code path.
To implement this distinction, rewrite LR register stored on stack
with 'ep' value in case of a successful resume, which is really in
every case unless some catastrophic failure occurred during suspend.
Without this change, Linux counts every resume as failed in
/sys/power/suspend_stats/fail

Add initial support for STM32MP2 SoCs family.
SoCs information are available here :
https://www.st.com/content/st_com/en/campaigns/microprocessor-stm32mp2.html
Migrate all MP1 related code into stm32mp1/ directory
Create stm32mp2 directory dedicated for STM32MP2 SoCs.
Common code to MP1, MP13 and MP25 is kept into
arch/arm/mach-stm32/mach-stm32mp directory :
- boot_params.c
- bsec
- cmd_stm32key
- cmd_stm32prog
- dram_init.c
- syscon.c
- ecdsa_romapi.c
For STM32MP2, it also :
- adds memory region description needed for ARMv8 MMU.
- enables early data cache before relocation.
During the transition before/after relocation, the MMU, initially setup
at the beginning of DDR, must be setup again at a correct address after
relocation. This is done in enables_caches() by disabling cache, force
arch.tlb_fillptr to NULL which will force the MMU to be setup again but
with a new value for gd->arch.tlb_addr. gd->arch.tlb_addr has been
updated after relocation in arm_reserve_mmu().
