firmware: zynqmp: Add PMC PGGS register read API
Add zynqmp_pm_get_pmc_global_pggs_reg() to read PMC Global PGGS3
and PGGS4 registers via firmware IOCTL. Supports IOCTL_READ_PGGS
as the preferred path and falls back to IOCTL_READ_REG for older
PLM firmware versions that do not support IOCTL_READ_PGGS.
