* changes:
feat(versal2): extended SMCCC payload for EEMI
feat(versal2): add support for platform management
feat(versal2): add dependency macro for PM
Until Versal, the extended SMCCC payload was supported only for
QUERY_DATA, while other APIs used the legacy SMCCC format.
In Versal Gen 2, all EEMI APIs are supported with extended SMCCC
payload only, enabling a simplified and efficient pass-through
implementation.
Also, set TFA_NO_PM to 0 to enable power management by default.

Currently BRBE is being disabled for Realm world in EL3 by
switching the SBRBE bit in mdcr_el3 register to 0b00.
The patch removes the switching of SBRBE bits, and adds
context switch of BRBCR_EL2 register.

Similar to the cpu_rev_var_xy functions, branching far away so early in
the reset sequence incurs significant slowdowns. Inline the function.

We strive to apply errata as close to reset as possible with as few
things enabled as possible. Importantly, the I-cache will not be
enabled. This means that repeated branches to these tiny functions must
be re-fetched all the way from memory each time which has glacial speed.
Cores are allowed to fetch things ahead of time though as long as
execution is fairly linear. So we can trade a little bit of space (3 to
7 instructions per erratum) to keep things linear and not have to go to
memory.
While we're at it, optimise the the cpu_rev_var_{ls, hs, range}
functions to take up less space. Dropping the moves allows for a bit of
assembly magic that produces the same result in 2 and 3 instructions
respectively.

The existing DSU errata workarounds hijack the errata framework's inner
workings to register with it. However, that is undesirable as any change
to the framework may end up missing these workarounds. So convert the
checks and workarounds to macros and have them included with the
standard wrappers.
The only problem with this is the is_scu_present_in_dsu weak function.
Fortunately, it is only needed for 2 of the errata and only on 3 cores.
So drop it, assuming the default behaviour and have the callers handle
the exception.

The errata in this patch are declared as runtime, but are never called
explicitly. This means that they are never called! Convert them to reset
errata so that they are called at reset. Their SDENs entries have been
checked and confirm that this is how they should be implemented.
Also, drop the the MIDR check on the a57 erratum as it's not needed -
the erratum is already called from a cpu-specific function.

Modify the FDT buffer for Rockchip devices to 384KiB. This is done to
allow us to pass mainline devicetrees with symbols through Arm Trusted
Firmware. 384KiB was chosen as 512KiB is very near the maximum
supported with the current reserved memory. As of kernel version 6.13,
the largest devicetree with symbols enabled is 215KiB, and the largest
Rockchip devicetree with symbols enabled is 176KiB

To pass SMMUv3 Realm Page 0 address to RMM
in Boot Manifest, BL31 needs to read SMMU_ROOT_IDR0
register. BL31 at EL3 runs in Root mode, but
CoreSight and peripherals at DEVICE0_BASE
(0x2000_0000) including SMMUv3 at 0x2B40_0000 are
mapped as MT_SECURE which results in RAZ access
to all SMMUv3 registers after enabling MMU.
This patch changes MT_SECURE mapping to EL3_PAS
resulting in MT_SECURE (ENABLE_RME = 0), and
MT_ROOT (ENABLE_RME = 1).

When RESET_TO_BL31 was enabled, CNTFRQ_EL0 was left uninitialized,
leading to incorrect system counter frequency settings. This
impacted timer-dependent components, such as SMMUv3, causing
initialization failures and unpredictable behavior.
To fix this, CNTFRQ_EL0 is now explicitly set using
plat_get_syscnt_freq2(), ensuring the correct system timer
frequency and proper initialization of dependent components.
