[v2,2/2] clk: keystone: syscon-clk: Add support for AM64 specific epwm-tbclk

Commit Message

AM64 has 9 instances of EPWM modules. And each instance has a clk to
Timer-Base sub-module that can be controlled by Control module. Update
the driver with all the 9 instance of clocks associated to
ti,am64-epwm-tbclk.
