[16/18] arch/sparc: Implement fb_is_primary_device() in source file

Commit Message

Thomas Zimmermann April 5, 2023, 3:05 p.m. UTC

Other architectures implment fb_is_primary_device() in a source
file. Do the same on sparc. No functional changes, but allows to
remove several include statement from <asm/fb.h>.
