In efuse mode, mt7915 only reads efuse values from FW which driver
need.
Add a debugfs knob to read addtional efuse values from a specific
field,
which is useful in some cases such as checking if rf values in
efuse
are properly burned.

An example of usage:
echo 0x400 > efuse_idx
hexdump -C eeprom

I'd prefer if we read the entire efuse and put it in a "otp" debugfs
file, like on older chips.
