MIPS: Remove CONFIG_ARCH_HAS_ILOG2_U{32,64}

Browse Source 
We declare CONFIG_ARCH_HAS_ILOG2_U32 & CONFIG_ARCH_HAS_ILOG2_U64 in
Kconfig, but they are always false since nothing ever selects them. The
generic fls-based implementation is efficient for MIPS anyway. Remove
the redundant Kconfig entries.
