Much of PSIL endpoint configuration for a given SoC can be known at compile time, therefore pass them for platform specific data instead of DT. Add per SoC's specific PSIL endpoint data. This is to bring driver in sync with upstream DT. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Reviewed-by: Grygorii Strashko <grygorii.strashko@ti.com>
