ppc/xive2: Allow 1-byte write of Target field in TIMA
When running PowerVM, the console is littered with XIVE traces regarding
invalid writes to TIMA address 0x100b6 due to a lack of support for writes
to the "TARGET" field which was added for XIVE GEN2. To fix this, we add
special op support for 1-byte writes to this field.
