[PATCH 1/2] arm64: dts: ti: k3-am62-main: Add epwm nodes

[Georgi Vlaev]

Add the compatible DT nodes for all EPWM instances
present in AM62 SoC. There is a total of 3 EPWM modules
available, sharing the same K3 IP as in AM64 SoC.

This also adds a required "ti,am62-epwm-tbclk" clock
provider node for the EPWM time-base clock.
