[PATCH 08/13] dt-bindings: serial: fsl-linflexuart: add clock input properties

[Larisa Grigore <larisa.grigore@oss.nxp.com>]

From: Radu Pirea <radu-nicolae.pirea@nxp.com>

Add optional support for the two clock inputs used by the LINFlexD UART
controller:
- "lin": LIN_BAUD_CLK
- "ipg": LINFLEXD_CLK

The clock inputs are kept optional to maintain compatibility with the
S32V234 platform.
