drm: fix drm_mipi_dbi build errors
[ Upstream commit eb7de496451bd969e203f02f66585131228ba4ae ]
drm_mipi_dbi needs lots of DRM_KMS_HELPER support, so select
that Kconfig symbol like it is done is most other uses, and
the way that it was before MIPS_DBI was moved from tinydrm
to its core location.
Fixes these build errors:
