[PATCH 3/3] arm64: dts: ti: Add TDA54 pinctrl header

[Yemike Abhilash Chandra <y-abhilashchandra@ti.com>]

Add TDA54_PINMUX() and the mux mode defines for use by TDA54 device tree
sources to build pinmux values.

Note: I understand that this patch goes through the SoC tree, but is
included here to give reviewers the full context.
