lib: sbi: Add variable-length unprivilege access functions
sbi_load/store_loop read/write variable-length buffer unprivileged.
Both function use the widest aligned 8/4/2/1 byte load/stores in each
loop to reduce the total number of iterations.
Also switch the scalar/vector misaligned handlers to make use of such
functions to simplify code.
Miscellaneous: remove the unnecessary [taddr] in inline assembly
