[PATCH] dt-bindings: serial: fsl-lpuart: Add imx93 compatible string

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

The lpuart on i.MX93 is derived from i.MX8ULP with some industrial
enhancements, it uses three compatible strings, so update the
compatible string for i.MX93. But for a few instants,
DTR_B, DSR_B, DCD_B and RIN_B pins are supported, so use one compatible
string fsl,imx93-lpuart-v2
