[PATCH 1/3] bbu: detect devices when devicefile has no /dev/ prefix as well

[Ahmad Fatoum]

Functions like imx6_bbu_internal_mmcboot_register_handler() are called
with devicefile either being the cdev name or with a full path.

There is no harm in trying to detect the devicefile in the former case
as well, so do it unconditionally and simplify the function as a result.
