DRIVER_VIDEO_IMX_IPUV3 selects VIDEO_VPL, which has a hard dependency
on OFTREE, so it is required to select this one, too.

to enable parallel display with the i.MX IPUv3.

HDMI support is not generally useful without EDID support.

Fixes:
In function `imx_hdmi_ioctl':
undefined reference to `edid_read_i2c'
undefined reference to `edid_to_display_timings'

The ipuv3 makes heavy use of video encoders internally to the SoC but
also external encoders are common. Switch to VPL support to be able
to handle these properly.

Compiling the tree with allyesconfig is helpful because different
compilers (gcc, clang) or static checkers (e.g. clang's scan-build)
can then process and check more code.

This patch introduces two new configuration symbols that Kconfig files
can depend on. That way, code that is only working where a cache or DMA
implementation exists can be opted out.
