FEAT_FGT also implements an extra trap bit in the MDCR_EL2 and MDCR_EL3 registers: bit TDCC enables trapping of use of the Debug Comms Channel registers OSDTRRX_EL1, OSDTRTX_EL1, MDCCSR_EL0, MDCCINT_EL0, DBGDTR_EL0, DBGDTRRX_EL0 and DBGDTRTX_EL0 (and their AArch32 equivalents). This trapping is independent of whether fine-grained traps are enabled or not. Implement these extra traps. (We don't implement DBGDTR_EL0, DBGDTRRX_EL0 and DBGDTRTX_EL0.)
