arm64: dts: ti: k3-j721e: Add general purpose timers

There are 20 general purpose timers on j721e that can be used for
things like PWM using pwm-omap-dmtimer driver. There are also
additional ten timers in the MCU domain which are meant for MCU
firmware usage and hence marked reserved by default.

The odd numbered timers have the option of being cascaded to even
timers to create a 64 bit non-atomic counter which is racy in simple
usage, hence the clock muxes are explicitly setup to individual 32 bit
counters driven off system crystal (HFOSC) as default.

These instantiation differs from J7200 and other SoCs with the device
IDs and clocks involved for muxing.
