pnv/xive2: Don't overwrite PC registers when writing TCTXT registers
When writing a register from the TCTXT memory region (4th page within
the IC BAR), we were overwriting the Presentation Controller (PC)
register at the same offset. It looks like a silly cut and paste
error.
We were somehow lucky: the TCTXT registers being touched are
TCTXT_ENx/_SET/_RESET to enable physical threads and the PC registers
at the same offset are either not used by our model or the update was
harmless.
Found through code inspection.
