Export the module alias information using the MODULE_DEVICE_TABLE()
macro in order to support auto-loading this module for devices that
support it.

Note, I tested this on a Pixel 6 device with the UFS patch series in
[1]. With both this patch and [1], the ufs-exynos module autoloads on
boot.

That part is redundant, you just copied result of of_device_id. No need
to resend just for this.

Well the point of including this snippet is to show that it's working.
Without this patch, `modinfo -F alias ufs-exynos.ko` doesn't return
anything. I'm fine with not including it either way though.

Thanks,
