[PATCH 22/22] firmware: ti: ti_sci_proc: Move processor ops into its own file

[Beleswar Padhi <b-padhi@ti.com>]

Extract the processor operations related functions and services from
ti_sci_core.c into its own file. This breaks down the single large
file into smaller logical files for better readability and maintenance.
