arch64: Fix the wrong constraint used for sve2p1 instructions.

The current implementation for the following SVE2p1 instructions add a
constraint in aarch64_opcode_table[] array, so that these instruction
might be immediately preceded in program order by a MOVPRFX instruction.

As per the spec these instruction does not immediately preceded in
program order by a MOVPRFX instruction and to fix this issue, SVE2p1_INSNC
macro is replaced with SVE2p1_INSN macro for the entries of these
instructions in aarch64_opcode_table[] array.

List of instructions updated: addqv, andqv, smaxqv, sminqv, umaxqv, uminqv,
eorqv, faddqv, fmaxnmqv, fmaxqv, fminnmqv and fminqv.
