video/drm: dsi: Add _NO_ to MIPI_DSI_* flags disabling features

Many of the DSI flags have names opposite to their actual effects,
e.g. MIPI_DSI_MODE_EOT_PACKET means that EoT packets will actually
be disabled. Fix this by including _NO_ in the flag names, e.g.
MIPI_DSI_MODE_NO_EOT_PACKET.

video/drm: Sync MIPI DSI Bus helper from Linux 4.9

This imports drivers/gpu/drm/drm_mipi_dsi.c from Linux kernel 4.9.
It can be very helpful when porting Linux mipi dsi driver to U-Boot.

DSI hosts expose operations which can be used by DSI peripheral drivers
to access associated devices.
