Instead of performing the hash calculation for the mac address by ourself, we
can simply reuse ether_crc and shift only the result according to our
needs.
The code was tested against the previous implementation by verifying both
implementations against each other in userspace for 16200000000 different
mac addresses, changing the vendor bits of the mac address first.

There is an ioctl() to write data to the firmware. After the data
is written, it reads the databack from the firmware and compares
against what the user wanted to write and prints an error message
if it doesn't match.
The problem is that verify process has a forever loop if the
firmware size is not a multiple of 4. I've fixed it by replacing
the bcm compare function with memcmp().
I have chopped out some debugging code in the process.

When it uses regulators the mms114 driver checks to see if it managed to
acquire regulators and ignores errors. This is not the intended usage and
not great style in general.
Since the driver already refuses to probe if it fails to allocate the
regulators simply make the enable and disable calls unconditional and
add appropriate error handling, including adding cleanup of the
regulators if setup_reg() fails.
