[0/3] soc: renesas: ARM errata updates

Message

Hi all,

This patch series updates the handling of ARM errata for affected
Renesas SoCs.

The first patch enables the new ARM_ERRATA_814220 for Cortex-A7, using
Kconfig logic.
The second patch moves enablement of ARM_ERRATA_754322 for Cortex-A9
from shmobile_defconfig to Kconfig logic, to make sure it's always
enabled when needed.
The third patch disables PL310_ERRATA_588369, as it doesn't affect any
Renesas SoCs.

The last patch is marked RFC, as I don't know the revision of PL310 on
EMMA Mobile EV2, and cannot test it on EMEV2.

Thanks for your comments!

Queuing the first one in renesas-devel for v5.4.

The other 2 are postponed.

Given it untangles dependencies, I'm also queuing the Kconfig part of patch 2.
The defconfig update will happen automatically during the refresh
after v5.4-rc1.
