Add compatible string "fsl,imx95-xcvr" for i.MX95 platform. The difference between each platform is in below table. +---------+--------+----------+--------+ | SOC | PHY | eARC/ARC | SPDIF | +---------+--------+----------+--------+ | i.MX8MP | V1 | Yes | Yes | +---------+--------+----------+--------+ | i.MX93 | N/A | N/A | Yes | +---------+--------+----------+--------+ | i.MX95 | V2 | N/A | Yes | +---------+--------+----------+--------+ On i.MX95, there are two PLL clock sources, they are the parent clocks of the XCVR root clock. one is for 8kHz series rates, named as 'pll8k', another one is for 11kHz series rates, named as 'pll11k'. They are optional clocks, if there are such clocks, then the driver can switch between them to support more accurate sample rates. As 'pll8k' and 'pll11k' are optional, then add 'minItems: 4' for clocks and clock-names properties. On i.MX95, the 'interrupts' configuration has the same constraint as i.MX93. Only on i.MX8MP, the 'resets' is required, but for i.MX95 and i.MX93 there is no such hardware setting.
