FSL-LSCH3 platforms can have multiple DDR clocks. LS2085A has one clock for
general DDR controlers, and another clock for DP-DDR. DDR driver needs to
change to support multiple clocks.

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.

Secondary cores need to be released from holdoff by boot release
registers. With GPP bootrom, they can boot from main memory
directly. Individual spin table is used for each core. Spin table
and the boot page is reserved in device tree so OS won't overwrite.

DP-DDR is used for DPAA, separated from main memory pool for general
use. It has 32-bit bus width and use a standard DDR4 DIMM (64-bit).

Previously the driver was only tested on Power SoCs. Different barrier
instructions are needed for ARM SoCs.

LS2085A is an ARMv8 implementation. This adds board support for emulator
and simulator:
Two DDR controllers
UART2 is used as the console
IFC timing is tightened for speedy booting
Support DDR3 and DDR4 as separated targets
Management Complex (MC) is enabled
Support for GIC 500 (based on GICv3 arch)

Freescale LayerScape with Chassis Generation 3 is a set of SoCs with
ARMv8 cores and 3rd generation of Chassis. We use different MMU setup
to support memory map and cache attribute for these SoCs. MMU and cache
are enabled very early to bootst performance, especially for early
development on emulators. After u-boot relocates to DDR, a new MMU
table with QBMan cache access is created in DDR. SMMU pagesize is set
in SMMU_sACR register. Both DDR3 and DDR4 are supported.
