MIPS: DEC: Update CPU overrides

Update CPU overrides for the DEC port with the recent additions, shaving
off some effectively dead code:

text data bss dec hex filename
5586952 233132 5990368 11810452 b43694 vmlinux.32-old
5581248 233140 5990368 11804756 b42054 vmlinux.32-new

text data bss dec hex filename
6036936 356648 10756544 17150128 105b0b0 vmlinux.64-old
6029896 360752 10756544 17147192 105a538 vmlinux.64-new

The data size increase is due to the special alignment requirement of
`init_thread_union' aka `.data..init_task' moving it up to the nearest
page boundary and making the amount of padding at its front rely on how
far within a page text ends.
