HV: add board specific cpu state table to support Px Cx

Browse Source 
Currently the Px Cx supported SoCs which listed in cpu_state_tbl.c is limited,
and it is not a wise option to build a huge state table data base to support
Px/Cx for other SoCs. This patch give a alternative solution that build a board
specific cpu state table in board.c which could be auto-generated by offline
tool, then the CPU Px/Cx of customer board could be enabled;

Hypervisor will search the cpu state table in cpu_state_tbl[] first, if not
found then go check board_cpu_state_tbl. If no matched cpu state table is found
then Px/Cx will not be supported;

Tracked-On: #3477
