ARM: dts: stm32: tune the HS USB PHYs on stm32mp15xx-dkx

This patch adds phy tuning parameters for usbphyc port0 (USBH controller)
and usbphyc port1 (OTG controller).
Phy tuning parameters are used to adjust the phy settings to compensate
parasitics, which can be due to USB receptacle, routing, and ESD protection
component.
