We can now add l4 abe interconnect hierarchy and ti-sysc data with ti-sysc driver supporting external optional clocks needed by mcpdm. This data is generated based on platform data from a booted system and the interconnect acces protection registers for ranges. To avoid regressions, we initially validate the device tree provided data against the existing platform data on boot. Note that mcpdm we now need to enable at module level only for devices that have the external pdmclk wired from the PMIC as the clock is needed for the module to be accessible.
