[PATCH v5 3/7] pwm: lpss: Include headers we are the direct user of

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

For the sake of integrity, include headers we are the direct
user of.

Replace the inclusion of device.h by a forward declaration
of struct device plus a (cheaper) of types.h as device.h is
an expensive include (measured in compiler effort).
