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.

Does S32V234 have the clocks? I don't understand the "maintain compatibility" in this context. Either you have or you have not clocks, which should be expressed in schema (: false, see example schema).

Just add the clocks to existing example. No need for new example for each new property.
