UEFI/BIOS for many ARM64 platforms support SDEI (Software Delegated Exception Interface) error source.

To leverage this feature, CONFIG_ARM_SDE_INTERFACE should be enabled in the kernel

Error without this feature:

sonic kernel: [    1.148536] GHES: Generic hardware error source: 0 notified via SDE Interface is not supported!
sonic kernel: [    1.157275] GHES: probe of GHES.0 failed with error -22

Verified by loading the image to see if this error is not seen
