This patch ensures that the TZPC (BP147) and TZASC-400 programming
happens for LS2085A SoC only when the desired config flags are
enabled and ensures that the TZPC programming is done to allow Non-secure
(NS) + secure (S) transactions only for DCGF registers.

The TZASC component is not present on LS2085A-Rev1, so the TZASC-400
config flag is turned OFF for now.
