drm/exynos: remove ifdeferry from initialization code
The patch replaces separate calls to driver (de)registration by
loops over the array of drivers. As a result it significantly
decreases number of ifdefs. Additionally it moves device registration
related ifdefs to header file.
Changelog v2:
- Rebased.
- Consider non kms driver in respect to infinite loop issue.
