Add new compatible ti,am62-eqep for TI K3 devices. If a device

Since there is only one functional and interface clock for eqep,
clock-names is not really required. The clock-name also changed
for TI K3 SoCs so make clock-names optional for the new compatible
since there is only one clock that is routed to the IP.

Really the clock should be named after the function it has in the IP
block - it looks like "sysoutclk" is more likely the name of the clock
routed to the IP rather than the role it has?

It is the name of the clock, though id like to keep sysclkout for
backwards compatibility, even though the name is confusing.

While we are here, add an example using ti,am62-eqep compatible.

I'm going to ack this even though the driver makes it seem like the
devices are compatible (there's no match data etc) given the addition of
the power domain and changes in required properties.
