Subject: [PATCH 05/10] MIPS: bmips: merge CPU options into one option

Instead of treating each flavour as an exclusive CPU to select, make
BMIPS the only option and let SYS_HAS_CPU_BMIPS* decide for which
flavours to include support.

Run tested on BMIPS3300 and BMIPS4350, only build tested for BMIPS4380
and BMISP5000.
