Extract/unify the two to a separate header (vesa.h). Given the fb's is in an uapi header, create the common header in uapi too. Note that instead of macros, an enum (vesa_blank_mode) is created. But the macros are kept too (they now expand to the enum constants), just in case someone in userspace performs some #ifdeffery.
