[PATCH 5.4 094/255] drm: fix drm_mipi_dbi build errors

[Greg Kroah-Hartman]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

[ 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:
