drm/mediatek: dsi: Use bitfield macros where useful



Instead of open coding bitshifting for various register fields,
use the bitfield macro FIELD_PREP(): this allows to enhance the
human readability, decrease likeliness of mistakes (and register
field overflowing) and also to simplify the code.
The latter is especially seen in mtk_dsi_rxtx_control(), where
it was possible to change a switch to a short for loop and to
also remove the need to check for maximum DSI lanes == 4 thanks
to the FIELD_PREP macro masking the value.

While at it, also add the missing DA_HS_SYNC bitmask, used in
mtk_dsi_phy_timconfig().
