hdata: Initialize SPIRA-H structure
Previous patch reduced reserved space in spira structure. Now its safe
to reduce the memory for spira section from 2K to 1K. Create separate
memory section with 1K size for SPIRA-H.
Also initialize SPIRA-H. FSP makes use of this information to pass various
boot time data (like SPIRA-S, etc) to host.
