The misc control register is 32bit wide, the used readw/writew accessors only mainipulate the low 16bit of this register. It currently doesn't matter as all the bit changed are located in the lower half, but together with the u32 variable used to hold the contents of the register it is seriously confusing. Switch to 32bit accessors to avoid any future breakage.
