ext4l: Extract freezer.h declarations into their own file

Browse Source 
Create include/linux/freezer.h with stub definitions for process
freezer functions used during suspend/hibernate. U-Boot doesn't
support process freezing, so these are no-ops.

Update compat.h to include freezer.h and remove duplicate definitions.
