Subject: [PATCH v1] scsi: ufs: exynos: Support module autoloading

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

$ modinfo -F alias out/linux/drivers/ufs/host/ufs-exynos.ko

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.
