ARM: tegra14: Changes for SMP and cluster switch
1. Enabled following kernel configuration for SMP on
fast cluster and cluster switching functionality:
TEGRA_LP2_ARM_TWD if HAVE_ARM_TWD && !TEGRA_RAIL_OFF_MULTIPLE_CPUS
ARM_SAVE_DEBUG_CONTEXT if PM_SLEEP
GIC_SET_MULTIPLE_CPUS if SMP
ARCH_TEGRA_HAS_ARM_SCU
ARCH_TEGRA_HAS_SYMMETRIC_CPU_PWR_GATE
ARM_CPU_SUSPEND if PM
2. For T14x, disable RAM repair bypass and power-up
CPU rail during Cluster 1(LP) to Cluster0( fast
cluster) switch.
2. For T14x, for IMMEDIATE_WAKE use WAITEVENT as wakeup
condition.
