We no longer unmask all HPD irqs, so we can drop the ugly per-platform
HPD IIR masking. IMR will prevent unsupported bits from appearing in
IIR.

this patch should come after
"drm/i915: Enable hpd logic only for ports that are present"

and here is the opportunity to rename this to SDE_DDI_HOTPLUG_MASK_ICP
or in a separate patch.

with the patch reorder,

While changing this, may fix the typo on subject: "per-platform"

The order should not matter. We already mask out all unwanted bits
from IIR via IMR, so whether or not the HPD level is visible in ISR
for some unused pin is irrelevant.
