Removes support in the ARM assembler for the unsigned variants of the VQ(R)DMLAH and VQ(R)DMLASH MVE instructions.
Previously GAS would accept .u32, .u16 and .u8 suffixes to the VQ(R)DMLAH and VQ(R)DMLASH
instructions, however the Armv8.1-M Mainline specification states that these functions only
have signed variations (.s32, .s16 and .s8 suffixes).
This is documented here:
