Subject: [PATCH 17/17] ARM: soc: dependency warnings for errata

The PL310_ERRATA_753970 and ARM_ERRATA_764369 symbols only make sense
when the base features for them are enabled, so select them
conditionally in Kconfig to avoid warnings like:

warning: (UX500_SOC_COMMON) selects PL310_ERRATA_753970 which has unmet direct dependencies (CACHE_PL310)
warning: (ARCH_TEGRA_2x_SOC && ARCH_TEGRA_3x_SOC && UX500_SOC_COMMON) selects ARM_ERRATA_764369 which has unmet direct dependencies (CPU_V7 && SMP)
