CPU_TTBR0_PAN has same effect as CPU_SW_DOMAIN_PAN, but it is compatible
to ARM_LPAE while CPU_SW_DOMAIN_PAN is not.
So it an optional way to go for ARM PAN solutions.

CONFIG_MEMCG is not required if device enables CONFIG_PSI. Change
CONFIG_MEMCG requirement to a conditional for either CONFIG_MEMCG or
CONFIG_PSI to be enabled. This saves memory resource on devices that
use PSI for memory pressure monitoring.

Android does not use per-cgroup CPU allowance for RT tasks feature.
Disable it so that RT task allowance is controlled globally using

Some platforms do not require this mitigation. For platforms that do,
this config requirement will continue to be enforced in CTS.

It's usually very helpful to enable AES-XTS and SHA-256 optimized with
the ARM crypto extensions (or x86 AES-NI and SHA-NI). AES-XTS is used
by file-based encryption; SHA-256 is used by dm-verity. I was a bit
surprised to see that these weren't already in the recommended configs.
This is change I6175e16261a7360d34de76735e06e21c41db58c8 applied to the
'q' directory.
