Convert the f71805f driver to use arrays of attributes. This shrinks the
compiled module from 12.0 kB to 9.6 kB. We certainly should do the same
for as many hardware monitoring drivers as possible.
This, together with a nice chip design by Fintek, makes this driver
very small, both in terms of number of lines of code and memory
consumption.
