hw/intc/arm_gicv3_its: Remove redundant ITS_CTLR_ENABLED define

Browse Source 
We currently define a bitmask for the GITS_CTLR ENABLED bit in
two ways: as ITS_CTLR_ENABLED, and via the FIELD() macro as
R_GITS_CTLR_ENABLED_MASK. Consistently use the FIELD macro version
everywhere and remove the redundant ITS_CTLR_ENABLED define.
