alpha: fix lit sign
according to the alpha arch reference, the literal field of an operate
instruction is unsigned:
If bit <12> of the instruction is 1, an 8-bit zero-extended literal
constant is formed by bits
<20:13> of the instruction. The l teral is interpreted as a positive
integer bet ween 0 and 255
and is zero-extended to 64 bits.
This patch fixes the mis-interpretation of the literal field.
