mfd: intel-lpss: Program REMAP register in PIO mode

commit d28b62520830b2d0bffa2d98e81afc9f5e537e8b upstream.

According to documentation REMAP register has to be programmed in
either DMA or PIO mode of the slice.

Move the DMA capability check below to let REMAP register be programmed
in PIO mode.
