Revert "drm/bridge: Select DRM_KMS_HELPER for DRM_PANEL_BRIDGE"

This reverts commit e3f18b0.

Selecting DRM_KMS_HELPER for DRM_PANEL_BRIDGE leads to:
WARNING: unmet direct dependencies detected for DRM_KMS_HELPER
  Depends on [m]: HAS_IOMEM [=y] && DRM [=m]
  ...

and builds with CONFIG_DRM=m will fail with the above kconfig
warns and then multiple linker error.
