docs: arm64: Document EL3 requirements for cpu debug architecture
This documents EL3 requirements for debug architecture. The register field
MDCR_EL3.TDA needs to be cleared for accesses into debug registers without
any trap being generated into EL3. CPU debug registers like DBGBCR<n>_EL1,
DBGBVR<n>_EL1, DBGWCR<n>_EL1, DBGWVR<n>_EL1 and MDSCR_EL1 are already being
accessed for HW breakpoint, watchpoint and debug monitor implementations on
the platform.
