MIPS: Remove usage of CSRC_R4K_LIB config option.
Manuel Lauss <manuel.lauss@gmail.com> writes: I introduced it as a fallback because early revisions of Alchemy hardware we shipped had a non-functional 32kHz timer and had to rely on the r4k timer instead. Previously the r4k timer was initialized regardless, but it's useless with the "wait" instruction. So long story short: I need either the on-chip 32kHz timer OR the r4k timer if the 32kHz one is unusable, but not both, and r4k timer is useless when au1k_idle is in use. The current in-kernel Alchemy boards all work with the 32kHz timer, so I'm not against removing R4K_LIB symbols. Signed-off-by: Steven J.
