OCC-OPAL Shared Memory Interface: Dynamic data updates

update the following in OPAL shared memory when any of these pieces
change:

* OCC State
* CPU Throttle status
* memory throttle status
* quick power drop
* power shifting ratio
* power cap type
* Min power cap
* Max power cap
* current power cap

*** When either throttle status bytes change alert OPAL of shared memory
  interface change via setting SCOM bits 3 in the ext_intr_reason field
  of OCC Misc register and bit 0 (core_ext_intr) to generate the interrupt.
