soc/intel/xeon_sp: Add _OSC ASL generation utils for IIO domains

For multi-SKU/SoC supports, IIO domain layouts are returned from FSP
HOBs. Add _OSC ASL generation utils so that static IIO domain layout
definition file per SKU/SoC are not needed any more.

The _OSC generation codes is a thin AML generation layer which
further invokes \_SB.POSC which is defined in ASL. The ASL handler
is able to handle boot-time generated info as parameters while keeps
good readability for the ease of maintenance. In this case, firmware
granted capabilities are calculated in boot time and passed to ASL
handler as parameters.

TEST=Build and boot on intel/archercity CRB
