AArch32: Add generic changes in BL1
This patch adds generic changes in BL1 to support AArch32 state.
New AArch32 specific assembly/C files are introduced and
some files are moved to AArch32/64 specific folders.
BL1 for AArch64 is refactored but functionally identical.
BL1 executes in Secure Monitor mode in AArch32 state.
NOTE: BL1 in AArch32 state ONLY handles BL1_RUN_IMAGE SMC.
