scsi/ufs: use macroes to control Hynix HID sys node.

Browse source 
For make Hynix HID driver disable for other vendors, we use macroes
to restrict its power.

note：
"manual_gc_status" is moved from
"/sys/device/platform/soc/4804000.ufshc/attributes" to
"/sys/device/platform/soc/4804000.ufshc/attributes_hid", APP or Script
need update this path.
