drm/i915/hsw, bdw: Add irq_pipe_mask, has_vga power well attributes
The pattern of a power well backing a set of pipe IRQ or VGA
functionality applies to all HSW+ platforms. Using power well attributes
instead of platform checks to decide whether to init/reset pipe IRQs and
VGA correspondingly is cleaner and it allows us to unify the HSW/BDW and
GEN9+ power well code in follow-up patches.
Also use u8 for pipe_mask in related helpers to match the type in the
power well struct.
v2:
- Use u8 instead of u32 for irq_pipe_mask. (Ville)
v3:
- Use u8 for pipe_mask in related helpers too for clarity.
