arm/trusted-firmware-a: Add support for spmd build option

Browse Source 
This patch adds generic dispatcher 'spmd' option for SPD along with
SPMD_SPM_AT_SEL2 build option.

 Config: SPD=spmd and SPMD_SPM_AT_SEL2=1. Indicates the SPMC component
 runs at the S-EL2
   - Add hafnium dependency
   - Set CTX_INCLUDE_EL2_REGS=1 and ARM_ARCH_MINOR=4
   - Set BL32 to hafnium image
   - Set SP_LAYOUT_FILE and ARM_SPMC_MANIFEST build parameters

 Config: SPD=spmd and SPMD_SPM_AT_SEL2=0. Indicates the SPMC component
 runs at the S-EL1 execution state.
