[PATCH v1 1/1] drm: Replace kernel.h with the necessary inclusions

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

When kernel.h is used in the headers it adds a lot into dependency hell,
especially when there are circular dependencies are involved.

Replace kernel.h inclusion with the list of what is really being used.
