Preparatory step for adding support for RTL8188EU devices.
Signed-off-by: Jakub Sitnicki <jsitnicki@xxxxxxxxx>

Notes:
An alternative approach to keeping a buffer that is big enough to hold
the efuse map of any of the supported chips would be to allocate the
efuse map on-the-go to pass it between read_efuse() and parse_efuse().
This would also reduce the memory footprint of struct rtl8xxxu_priv.
