soc/qualcomm/sc7180: Adapt to recent API changes

Definitions were moved so that now device/mmio.h needs to be included
instead of arch/mmio.h. Also, don't use le32 conversion.

This follows the activities of commit 55009af42 (Change all
clrsetbits_leXX() to clrsetbitsXX()) and commit 1c371572188 (mmio: Add
clrsetbitsXX() API in place of updateX()).
