Subject: [PATCH v4] dt-bindings: pinctrl: Add SA8255p TLMM

Add compatible for TLMM block representing support on SA8255p.

SA8255p uses the same TLMM block as SA8775p however the ownership
of pins are split between Firmware VM and Linux VM on SA8255p. For
example, pins used by UART are owned and configured by Firmware VM
while pins used by ethernet are owned and configured by Linux VM.
Therefore, adding a sa8255p specific compatible to mark the difference.
