opal-api: Add OPAL call to handle abnormal reboots.
This patch adds a new OPAL call OPAL_CEC_REBOOT2 which will
be used to handle abnormal reboot/termination by kernel host.
This call will allow host kernel to pass reboot type and additional
debug data which needs to be captured/saved somewhere (for later
analysis) before going down.
Currently it will support two reboot types (0). normal reboot, that
will behave similar to that of opal_cec_reboot() call, and
(1). platform error reboot, that will trigger a system checkstop
using xscom address and FIR bit information obtained via device-tree
property 'ibm,sw-checkstop-fir'.
For unsupported reboot type, this call will do nothing and return
with OPAL_UNSUPPORTED.
In future, we can overload this call to support additional reboot types.
