Coresight: ETMv4: Prevent TRCRSCTLR0&1 from being accessed
1. TRCRSCTLRn - Resource Selection Control Registers n=0~1 are reserved,
we shouldn't access them.
2. The max number of 'n' here is defined in TRCIDR4.NUMRSPAIR whoes value
indicates the number of resource selection *pairs*, and 0 indicates
one resource selection pair, 1 indicates two pairs, and so on ...
So, the total number of resource selection control registers which we can
access is (TRCIDR4.NUMRSPAIR * 2)
