[PATCH v2 1/3] drm/sysfb: Split source file

[Thomas Zimmermann]

Split drm_sysfb_helper.c into two source files. There's now one
source file for the mode-setting pipeline and one source file for
module meta data. Prepares for adding additional source code to
sysfb helpers.

v2:
- fix typo in commit message (Javier)
