arm64: dts: qcom: sm8250: fix PCIe bindings to follow schema

Replace (unused) enable-gpio binding with schema-defined wake-gpios. The
GPIO line is still unused, but at least we'd follow the defined schema.

While we are at it, change perst-gpio property to follow the preferred
naming schema (perst-gpios).
