[PATCH 1/2] pwm: lpss: Move namespace import into a header

["Uwe Kleine-König" <u.kleine-koenig@baylibre.com>]

Each user of the exported symbols related to the pwm-lpss driver needs
to import the matching namespace. So this can just be done in the header
together with the prototypes.

This fixes drivers/pinctrl/intel/pinctrl-intel.c which failed to import
that namespace before. (However this didn't hurt because the pwm-lpss
module namespace isn't used; see the next commit.)
