GICv2: Add driver API to set PE target mask

The PE target mask is used to translate linear PE index (returned by
platform core position) to a bit mask used when targeting interrupts to
a PE, viz. when raising SGIs and routing SPIs.

The platform shall:

  - Populate the driver data with a pointer to array that's to contain
    per-PE target masks.

  - Invoke the new driver API 'gicv2_set_pe_target_mask()' during
    per-CPU initialization so that the driver populates the target mask
    for that CPU.

Platforms that don't intend to target interrupts or raise SGIs need not
populate this.
