Varun Wadekar e272c61ce8 fix(tegra194/ras): remove incorrect erxctlr assert
The ERXCTLR_EL1 register reads are RES0 for some error records
leading to a false assert on a read back.

This patch removes the assert on reading back the ERXCTLR_EL1
register to fix this issue.

Scott Branden 4ce3e99a33 fix: libc: use long for 64-bit types on aarch64
Use long instead of long long on aarch64 for 64_t stdint types.
Introduce inttypes.h to properly support printf format specifiers for
fixed width types for such change.

Pali Rohár 30e8fa7e77 refactor(plat/ea_handler): Use default ea handler implementation for panic
Put default ea handler implementation into function plat_default_ea_handler()
which just print verbose information and panic, so it can be called also
from overwritten / weak function plat_ea_handler() implementation.

Replace every custom implementation of printing verbose error message of
external aborts in custom plat_ea_handler() functions by a common
implementation from plat_default_ea_handler() function.

David Pu ebd720d0b0 Tegra194: ras: split up RAS error clear SMC call.
In order to make sure SMC call is within 25us, this patch reduces number of RAS
errors accessed to 8 at most for each SMC call and takes a input/output
parameter to specify in progress RAS error record index.

The measured SMC call latency is about 20us under Linux test kernel driver.

Varun Wadekar 0d8511953e 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.
