ArmPkg: Prevent SgiId from setting RES0 bits of GICD_SGIR
GICD_SGIR is a 32-bit register, of which INTID is bits [3:0] and Bits
[14:4] is RES0. Since SgiId parameter in the function ArmGicSendSgiTo ()
is UINT8, mask unused bits of SgiId before writing to the GICD_SGIR
register to prevent accidental setting of the RES0 bits.
