BCM1250_M3_WAR is depending on CONFIG_CONFIG_SB1_PASS_2_WORKAROUNDS.
So using this option directly lets and remove define.

SB1250 uart bug is related to PASS 2 workarounds. Use config
CONFIG_SB1_PASS_2_WORKAROUNDS directly and get rid of SIBYTE_1956_WAR.

Neither MIPS4K_ICACHE_REFILL_WAR nor MIPS_CACHE_SYNC_WAR are implemented,
so removing defines for it won't change anything.

There are some common header files which are referenced locally
with #includenext method, includenext is tricky method and only
used on mips platform.
This patech removes includenext method, replace it with defailed
pathname prefix for header files.
This patch passes to compile on all mips platform with defconfig,
and is verified on my loongson64 box.
Changes:
--------
v2:
- Fix compiling issue on malta platform

R5432_CP0_INTERRUPT_WAR is defined as 0 for every system we support, and
so the workaround is never used. Remove the dead code.

Hardcode the absence of the MIPS16e2 ASE for all the systems that do so
for the MIPS16 ASE already, providing for code to be optimized away.

The `cpu_has_fpu' feature flag must not be hardcoded to 1 or the `nofpu'
kernel option will be ignored. Remove any such overrides and add a
cautionary note. Hardcoding to 0 is fine for FPU-less platforms.

Most supported systems currently hardwire cpu_has_dsp to 0, so we also
can disable support for cpu_has_dsp2 resulting in a slightly smaller
kernel.
