[PULL 13/66] target/mips/mips-defs: Use ISA_MIPS32R6 definition to check Release 6

[Philippe Mathieu-Daudé <f4bug@xxxxxxxxx>]

Use the single ISA_MIPS32R6 definition to check if the Release 6
ISA is supported, whether the CPU support 32/64-bit.

For now we keep '32' in the definition name, we will rename it
as ISA_MIPS_R6 in few commits.
