feat(bl2): support RESET_TO_BL2 and ENABLE_RME

When RSE is used as the root of trust along with CPU that supports RME
there is a need to enable both RESET_TO_BL2 and ENABLE_RME.

In current bl2_main there are two different code paths for RESET_BL2,
one handles BL2 running in EL1 and other for BL2 running in EL3.

When RME is enabled, BL2 always runs at EL3 but the current flow calls
bl2_early_platform_setup2, bl2_plat_arch_setup instead of
bl2_el3_early_platform_setup, bl2_el3_plat_arch_setup. Adding RME,
TRANSFER_LIST, ROMLIB support in bl2_el3_* helpers makes
arm_bl2_el3_setup.c almost identical to arm_bl2_setup.c.

This patch removes bl2_el3_plat helpers and related files. Now different
combinations of RESET_TO_BL2, ENABLE_RME are handled in common bl2_setup
routines in arm_bl2_setup.c. This helps to have common place to support
new features and build flags for BL2 irrespective of which EL the BL2
runs.

BREAKING-CHANGE: This patch also changes all existing platform files and
functions that use format bl2_el3_* to bl2_plat helpers. If any platform
or out-of-tree platforms that need to support running BL2 in EL1 or EL3
must now handle it in bl2_early_platform_setup2 and bl2_plat_arch_setup.

fix(nxp/common/setup): fix total dram size checking

total_dram_size should be signed value because it is equal to return
value of init_ddr(), so if it is lower or equal zero, report
error as DDR is

fix(nxp/common/setup): fix total dram size checking

total_dram_size should be signed value because it is equal to return
value of init_ddr(), so if it is lower or equal zero, report
error as DDR is not initialized correctly.
