target/arm: Rename cp15.c6_rgnr to pmsav7.rnr
Almost all of the PMSAv7 state is in the pmsav7 substruct of the ARM CPU state structure. The exception is the region number register, which is in cp15.c6_rgnr. This exception is a bit odd for M profile, which otherwise generally does not store state in the cp15 substruct. Rename cp15.c6_rgnr to pmsav7.rnr accordingly.
