[PATCH 4/4] arm64: dts: st: Add UCPD node on stm32mp251

Add ST UCPD Type-C block node on stm32mp251. The UCPD integrates the
physical layer of the Power Delivery (PD), with CC signaling method,
for operation with Type-C cables. Vbus and Vconn control is performed
using an external chip, usually ST TCPP01/TCPP02/TCPP03 or similar.
The UCPD Rp/Rd resistor trimming values are part of OTP, add the nvmem
subnode and include a phandle to it.
