Add support for panels that use the DPI interface.
ILI9341 has onboard RAM so the assumption made here is that all such
panels support pixel upload over DBI.
The presence/absense of the Device Tree 'port' node decides which
interface is used for pixel transfer.

The MI0283QT panels use a ILI9341 controller so it makes sense to merge
it with the other ili9341 code.
The DRM driver name is ABI, so that is retained.

Move the driver to drm/panel and take advantage of the new panel support

ie. they have a custom controller for their display. Some
even pretend to be one controller, but reading the register contents,
it's doubtful that this is true and it's more likely to be a clone.

mipi-dbi depends on the CMA helper through it's use of
drm_fb_cma_get_gem_obj(). This is an unnecessary dependency to drag in for
drivers that only want to use the MIPI DBI interface part.
Avoid this by open coding the function.

The tinydrm helper is going away so move it into the only user mipi-dbi.

The SPI event tracing can dump the buffer now so no need for this.
Remove the debug print from tinydrm_spi_transfer() since this info can be
gleaned from the trace event.

byte swapping on little endian
machines with SPI controllers only supporting 8 bits per word.
Other changes:
- No need to initialize ret
- No need for the WARN since mipi-dbi only uses 8 and 16 bpw.
- Use spi_message_init_with_transfers()

This means that tinydrm_spi_bpw_supported() can be removed.

No need for this comment.
