Combine MT6797 pin controller document into MT6779 one. reg and
reg-names property constraints are set using conditionals.
A conditional is also used to make interrupt-related properties
required on the MT6779 pin controller only, since the MT6797
controller doesn't support interrupts (or not yet, at least).
drive-strength and slew-rate properties which weren't described
in the MT6779 document before are brought in from the MT6797 one.
Both pin controllers share a common driver core so they should
both support these properties.

Qualcomm pinctrl Devicetree bindings changes for v6.2
Big set of refactoring and improving Qualcomm pin controller bindings:
1. Convert several bindings from TXT to DT schema format: MDM9615,
MSM8974, MSM8994, MSM8996, MSM8998, SC7180, SDM630, SDM845, SM8150.
2. Refactor existing DT schema bindings to be consistent and similar to
each other, remove unneeded pieces (provided by common bindings) and
unify the style.
2. Fix matching of the existing DT schema bindings, so they properly
validate the DTS. When looking for pin configuration (children
nodes), be specific and expect "state" or "pins" suffixes (depending
on the nesting. This allows the schema later to properly parse also
GPIO hogs, although it is not yet implemented. The changes require
aligning the DTS to new layout, but it does not break any
compatibility.
