opal-prd: Fix opal-prd command line options
opal-prd: Fix opal-prd command line options

HBRT OCC reset interface depends on service processor type.
  FSP -> reset_pm_complex()
  BMC -> process_occ_reset()

We have both `occ` and `pm-complex` command line interfaces.
This patch adds support to dispaly appropriate message depending
on system type.
  FSP -> opal-prd occ         --> display error message
  FSP -> opal-prd pm-complex  --> Call pm_complex_reset()
  BMC -> opal-prd occ         --> Call process_occ_reset()
  BMC -> opal-prd pm-complex  --> display error message
