lib: Drop _fifo from the name of various sbi_tlb_fifo_xyz() functions

Browse source 
This patch drops _fifo from the name of various sbi_tlb_fifo_xyz()
functions because all these functions deal with remote TLB managment
and FIFO is the per-HART data structure used internally by remote
TLB implementation.
