There are 20 general purpose timers on j784s4 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.
Though the count is similar to J721e/J7200/j721s2, the device IDs
and clocks used in j784s4 are different with the option of certain
clocks having options of additional clock muxes. Since there is very
minimal reuse, it is cleaner to integrate as part of SoC files itself.
The defaults are configured for clocking the timers from system
clock(HFOSC0).
