thermal: rcar: fix ENR register value

Browse Source 
On R-Mobile APE6, since it has 3 thermal zones, ENR register
has enable bits in bit 19-16, bit 11-8 and bit 3-0.

However, on R-Car gen2, since it has 1 thermal zone, ENR register has
enable bits in bit 3-0. (In other words, the write value should always
be 0 for bit 31-4 of ENR register.)

So, this patch fixes the ENR register value using I/O resource sets.
