xscom_read and xscom_write return OPAL_SUCCESS if they worked, and
OPAL_HARDWARE if they didn't. This doesn't provide information about why
the operation failed, such as if the CPU happens to be asleep.
This is specifically useful in error scanning, so if every CPU is being
scanned for errors, sleeping CPUs likely aren't the cause of failures.
So, return OPAL_WRONG_STATE in xscom_read and xscom_write if the CPU is
sleeping.

On P8 we got it a bit wrong and would fall into a workaround for P8 DD1
HILE setting if other bits were set in the flags to OPAL_REINIT_CPUS,
limiting our opportunity to extend it in the future.

It's not necessary and not in PAPR. HostBoot should probably do a
similar change.

Additionally, we put in some skeleton docs for what's coming,
key points being that this is for P9 and above, relies on a device
being present in the device tree and is modelled on the PAPR calls.
