aarch64: Add WFET instruction for Armv8.7-a
This patch adds new to Armv8.7 WFET instruction which take one operand:
WFET <Xt>
Where:
<Xt> is 64-bit name of the general-purpose source register, encoded in the
"Rd" field.
For more details regarding WFET (Wait For Event with Timeout) instruction for
Armv8.7-a please refer to Arm A64 Instruction set documentation for Armv8-A
architecture profile, see document pages 565 of [0].
