Partially revert commit e0c14a260d66ba35935600d6435940a566fe806b
and turn off LL/SC when building a pure microMIPS kernel. This is
a temporary fix until the cmpxchg assembly macro functions are
re-written to not use the HI/LO registers in address calculations.
Also add .insn in selected user access functions which would
otherwise produce ISA mode jump incompatibilities. This is also a
temporary fix.

All synthesizable CPU cores that could be loaded into a SEAD3's FPGA are
MIPS32 or MIPS64 CPUs that have ll/sc.

Commit f7ade3c168e4f437c11f57be012992bbb0e3075c ("MIPS: Get rid of
CONFIG_CPU_HAS_LLSC") did what it promised to do. But since then that
macro and its Kconfig symbol popped up again. Get rid of those again.

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

Nobody seems to be interested anymore and upstream also never had an
ethernet driver.

More information about the SEAD-3 platform can be found at
<http://www.mips.com/products/development-kits/mips-sead-3/>
on MTI's site. Currently, the M14K family of cores is what
the SEAD-3 is utilised with.
