soc/amd/picasso/acpi: Improve PCI Interrupt Link Devices

The PCI interrupt devices were only partially implemented.
* Lacked support for _DIS to disable the bus. Something the kernel does
  while booting.
* Lacked support for APIC vs PIC. This means the devices can only be
used when using the PIC. By looking at the PMOD variable we can handle
both PIC and APIC. This means we can stop hard coding the PCI interrupt
numbers in the ACPI tables.
* I removed INT[E-H] since they are not used.

BUG=b:139429446, b:147042464
BRANCH=none
TEST=Boot with both the APIC and PIC and saw that the link devices work
as expected:
