While I agree about the CONFIG_MIPS64 => CONFIG_64BIT replacement, I
wonder if CONFIG_MIPS32_R2 shouldn't rather be CONFIG_CPU_MIPSR2
(maybe even the existing CONFIG_CPU_MIPS32_R2 are wrong here).
CPU_XLP selects CPU_MIPSR2, and CPU_LONGSOON1 selects CPU_MIPS32 and
CPU_MIPSR2, so they should probably be treated the same way as
CPU_MIPS32_R2 (for e.g. the di/ei availability), but since all three
are choice values, there can't be CPU_MIPS32_R2 selected if
CPU_LONGSOON1 or CPU_XLP is chosen.
