soc/amd/picasso: Move PMOD global variable to globalnvs.asl
Global variable `PMOD` that stores the interrupt mode used by OS is required by all mainboards. This change moves the variable definition to globalnvs.asl under picasso. Additionally, ACPI spec says that BIOS should assume interrupt mode as PIC until _PIC() method is called by OS. Thus, this change also updates the default value of PMOD as 0 i.e. PIC mode.
