Prevent the FSP from writing its default SVID SDID values of 8086:7270
for internal devices as this locks most of the registers. Allows the
subsystemid values set in devicetree to be used.
A description of this SSID table override behavior, along with example
code, is provided in the TigerLake FSP Integration Guide, section
15.178 ("SI_CONFIG Struct Reference").
The xHCI and HDA devices have RW/L registers rather than RW/O registers.
They can be written to multiple times but cannot be modified after
being locked, which happens during FspSiliconInit. Because coreboot
populates subsystem IDs after SiliconInit, these devices specifically
must be written beforehand or will otherwise be locked with their
default values of 0:0.
TGL also introduces parameters for customizing the default SVID:SSID.
These must be set or it will still use the FSP defaults.
Tested by checking lspci output on System76 darp7 (TGL-U).

coreboot always assumes that BSP APIC ID will always be 0 but as
per Intel 64 and IA-32 Architectures Software Developer’s Manual
Volume 3: 8.4.1 BSP and AP Processors, it says that BSP can
be any processor whose index/APIC ID might not be 0.
To handle this situation, init_cpu call is required to modify to
handle dynamic detection of APIC ID from BSP instead of hardcoding
always through devicetree. Function has been updated to create
a new node with actual BSP APIC ID when devicetree doesn't contain
APIC ID defined. In case APID ID is defined, function will use a
node with the APIC ID defined in devicetree.
Changes also requires to remove "lapic 0" hardcoding from devicetree
to allow code to fill BSP APIC ID dynamically. Otherwise coreboot
will create an extra node for CPU with APIC ID 0 and it'll show as a
extra node in kernel. This will cause kernel to report wrong (extra)
core count information then actually present.
BUG=None
BRANCH=None
TEST=Boot the JSL system and observe there is no functional impacts.
Without this CL kernel core count in `lscpu` = 3
With this CL, kernel core count is corrected to 2.
