RISC-V: capitalise CMO op macros

The CMO op macros initially used lower case, as the original iteration
of the ALT_CMO_OP alternative stringified the first parameter to
finalise the assembly for the standard variant.
As a knock-on, the T-Head versions of these CMOs had to use mixed case
defines. Commit dd23e9535889 ("RISC-V: replace cbom instructions with
an insn-def") removed the asm construction with stringify, replacing it
an insn-def macro, rending the lower-case surplus to requirements.
As far as I can tell from a brief check, CBO_zero does not see similar
use and didn't require the mixed case define in the first place.
Replace the lower case characters now for consistency with other
insn-def macros in the standard and T-Head forms, and adjust the
callsites.
