Add a new compatible string "ti,am654-ehrpwm" to support EHRPWM IP on
TI AM654 SoC.

K3 devices have the same EHRPWM IP as OMAP SoCs. Enable driver to be built
for K3 devices. Also, drop reference to AM33xx in help text, as IP is
found on multiple TI SoCs.

It would be great to be able to compile this driver with COMPILE_TEST.
>From a quick look the following would be appropriate:

	depends on ARCH_OMAP2PLUS || ARCH_DAVINCI_DA8XX || ARCH_K3 || COMPILE_TEST
	depends on HAVE_CLK && HAS_IOMEM
 
Best regards

Thanks for the suggestion! I will send a separate patch on top of this
series to enable COMPILE TEST for this driver and other TI PWM drivers.
