lib/crypto: gf128mul: Remove unused 4k_lle functions
Remove the 4k_lle multiplication functions and the associated
gf128mul_table_le data table. Their only user was the generic
implementation of GHASH, which has now been changed to use a different
implementation based on standard integer multiplication.
