mb/*/brya/adlrvp: Remove hardcoding of BSP APIC ID

coreboot always assumes that BSP APIC ID will be 0 and core enumeration
logic will look for lapic id from the mainboard.

As per Intel 64 and IA-32 Architectures Software Developer’s Manual
Volume 3: 8.4.1 BSP and AP Processors, this assumption might
not hold true and we may have any other core as BSP. To handle this,
we need to remove hardcoding of APIC ID 0 from mainboard.

BUG=None
BRANCH=None
TEST=Check if there is no functional impact on the board.
