Tegra194: SiP: clear RAS corrected error records
This patch introduces a function ID to clear all the RAS error
records for corrected errors.
Per latest requirement, ARM RAS corrected errors will be reported to
lower ELs via interrupts and cleared via SMC. This patch provides
required function to clear RAS error status.
This patch also sets up all required RAS Corrected errors in order to
route RAS corrected errors to lower ELs.
