[PATCH v1] arm: socfpga: soc64: boot_scratch_cold 8 and 9 usage documentation

[alif.zakuan.yuslaimi at intel.com]

From: Alif Zakuan Yuslaimi <alif.zakuan.yuslaimi at intel.com>

The boot_scratch_cold register is generally used for passing
critical system info between SPL, U-Boot and Linux.

Documenting the usage of boot_scratch_cold8 and boot_scratch_cold9
sticky registers for capturing the Uncorrected Errors
(UE) and the UE Address. This is to avoid overlapping usage in the
code for S10 and Agilex.
