aarch64: Fix sve2p1 extq instruction operands.
This patch fixes the syntax of sve2p1 "extq" instruction by modifying the operands
count to 4. A new operand AARCH64_OPND_SVE_UIMM4 is defined to handle the 4th
argument an 4-bit unsigned immediate of extq instruction. The instruction encoding
is updated to use constraint C_SCAN_MOVPRFX, to enable "extq" instruction to immediately
precede in program order by a MOVPRFX instruction. Also removed the unused operand
AARCH64_OPND_SVE_Zm_imm4.
