sh: make constant unsigned to avoid narrowing

Shifting into the sign bit of a 32 bit int and then converting to a unsigned
type is less straight forward than just shifting an unsigned value.

opcodes/ChangeLog:

2016-05-31  Trevor Saunders  <tbsaunde+binutils@tbsaunde.org>

	* sh-opc.h (ARCH_SH_HAS_DSP): Make the shifted value an unsigned
	constant.
