mips: remove syscall table entries

Firoz Khan · paulburton · commit 6a00cb6175a4 · 2018-12-14T11:19:01.000-08:00
The config flag - CONFIG_MIPS_MT_FPAFF uses to check whether which
syscall entries need to be used in scall32-o32.S file.

One of the patch in this patch series will generate syscall table
file. But CONFIG_MIPS_MT_FPAFF flag will add more complexity in the
script to generate the syscall table file.

In order to come up with a common implementation across all archit-
ecture, we need to remove mipsmt_sys_sched_setaffinity and mipsmt-
_sys_sched_getaffinity from the table and define it in other way.
