Current code actually clears more bits than PALMAS_SMPS12_CTRL_MODE_ACTIVE_MASK bits.

Hi Graeme,

I'm wandering if we need to clear the status bits.
Current code actually clears bit[7:4] and bit[1:0] and set bit[7:6] to bit[3:2].
Looks like we only need to clear PALMAS_SMPS12_CTRL_MODE_ACTIVE_MASK bit[1:0] bits here.
and this change makes the intent more clear.

I don't have this hardware,
I'd appreciate if you can test this patch if you think this change ok.

Regards,
Axel
