dev-arm: Rewrite SMMUv3 Commands

This patch is rewriting the SMMUv3::processCommand method for the
following reasons:

* Command names were not matching spec
* Command encoding/opcode was wrong

The patch is not adding any new command: there is still a subset of
unimplemented commands; those are:

* CMD_TLBI_EL3_ALL
* CMD_TLBI_EL3_VA
* CMD_TLBI_EL2_ALL
* CMD_TLBI_EL2_VA
* CMD_TLBI_EL2_VAA
* CMD_TLBI_EL2_ASID

which require StreamWorld support, and

* CMD_ATC_INV
* CMD_PRI_RESP
* CMD_RESUME
* CMD_STALL_TERM

which require in sequence: ATS, PRI, Stall Model support
