Import Linux header file include/uapi/linux/arm_sdei.h from kernel
v5.3 release.

This is to prepare for qemu SDEI emulation.

Some issues with this.  First linux-headers is for linux as a host.
This is for linux as a guest, so belongs in include/standard-headers.

Second, please add to scripts/update-linux-headers.sh in a 1st patch,
then add the file in the second patch.
