[PATCH v2 09/10] board: imx8mp_evk: enable USB PD sink via TCPCI

[Peng Fan (OSS)]

From: Peng Fan <peng.fan at nxp.com>

Add PTN5110 TCPCI node on I2C3 with USB-C connector configured as
sink-only. The sink PDOs advertise 5V/3A fixed and 5-20V/2.25A
variable, enabling PD negotiation up to 45W.

Enable TYPEC_TCPM, TYPEC_TCPCI and CMD_TCPM in defconfig.
