On TI's AM654/J721e SoCs, certain clocks can be gated/ungated by setting
a single bit in SoC's System Control Module registers. Sometime more
than one clock control can be in the same register.
Add a driver to support such clocks using syscon framework. Driver
currently supports controlling EHRPWM's TimeBase clock(TBCLK) for AM654
SoC.

In K2G, the clock handling is done through firmware executing on a
separate core. Linux kernel needs to communicate to the firmware
through TI system control interface to access any power management
related resources, including clocks.
The keystone sci-clk driver does this, by communicating to the
firmware through the TI SCI driver. The driver adds support for
registering clocks through DT, and basic required clock operations
like prepare/get_rate, etc.
