Re: [PATCH v2 1/2] dt-bindings: PCI: fsl,imx6q-pcie: Explicitly deprecate reset-gpio

The binding references snps,dw-pcie-common.yaml which already deprecates
"reset-gpio", however mentioning this property here lacks this mark thus
code is confusing and suggests property is not deprecated.

OTOH, the property cannot be removed from this schema, because it is an
ABI implemented by Linux kernel in gpiolib-of.c in backwards-compatible
map between compatibles, "reset-gpio" and "reset-gpio-active-high"
properties.

This creates code and binding which is not obvious to follow, so rewrite
it and be more explicit about:
1. Deprecation of "reset-gpio",
2. Relation that "reset-gpio-active-high" is used only for that property
   and not proper "reset-gpios".

Changes in v2:
1. Rewrite the commit completely after Sherry Sun comments - keep the
   property, but add "not" clause to forbid usavge of
   "reset-gpio-active-high" and "reset-gpios".
2. Because of above not adding Richard's ack.

v1:
