[PATCH] dt-bindings: PCI: qcom-ep: Fix PERST register description

[Johan Hovold]

The 'qcom,perst-regs' property holds a single phandle array with the
phandle of the TCSR syscon and offsets of the two PERST registers, but
the current schema does not capture this.

Update the binding to describe the single phandle array and its three
elements.

It's not necessarily a fix, the original code was correct, just this one
is better. :)
