Since the write value should always be 0 for bit 31-4 of ENR register
on R-Car H2, this patch fixes the value.

While your patch is correct for R-Car gen2, this driver is also used on
R-Mobile APE6 (r8a73a4), which does have 3 thermal zones.
So I think you should count the other I/O resource sets to calculate
the correct mask.

when I'm talking to journalists I just say "programmer" or something like that.
