target-ppc: disable unsupported modes for SPR_CTRL/SPR_UCTRL
The Figure 17 "SPR encodings" of the PowerISA 2.07 describes CTRL SPR as:
priviledged
# spr5-9 spr0-4 name mtspr mfspr len cat
136 00100 01000 CTRL - no 32 S
152 00100 11000 CTRL yes - 32 S
According to this chart, the hypervisor's CTRL (#152) does not support
reading, the user-space's CTRL (UCTRL, #136) does not support writing.
This replaces unsupported operations with the default SPR_NOACCESS hook.
