Subject: [PATCH v2] MIPS: Get rid of CONFIG_CPU_HAS_LLSC again

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.

0) This version fixes an embarrassing dangling "#endif" spotted by
Jonas. Thanks for that! Still untested.
