dt-bindings: regulator: add PF0900 regulator yaml 



Add device binding doc for PF0900 PMIC driver.

Can not get the I2C_CRC_EN config by reading register. If the PMIC
OTP_I2C_CRC_EN is enable, need to add the nxp,i2c-crc-enable property.

description:

  The PF0900 is a power management integrated circuit (PMIC) optimized

  for high performance i.MX9x based applications. It features five high

  efficiency buck converters, three linear and one vaon regulators. It

  provides low quiescent current in Standby and low power off Modes.
