video/drm: dsi2: disable BTA during auto calculation training

when DSI operates in auto calculation mode,it sends a dsc read
get_scanline request to the peripheral devices to automatically
calculate phy_max_rd_time_auto during the auto calculation training.
However,if the peripheral devices,such as a bridge chip or some panel,
lack the capability to respond to read-back requests,they cannot respond
to the DSI host’s BTA,leading to the signal control not being properly
returned to the DSI host,Therefore,the BTA function should be disabled
in such case.

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

As described in link:

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.
