Every chip family except RTL8723AU has a copy of the efuse dumping code. Remove this and dump the efuse from a single place using a new function rtl8xxxu_dump_efuse(). Also, use print_hex_dump() to print the efuse instead of a loop and dev_info(). It shows the ASCII interpretation of the bytes, which is nice.
