drm/bridge/synopsys: dsi: add dual-dsi support
Allow to also drive a slave dw-mipi-dsi controller in a dual-dsi
setup. This will require additional implementation-specific
code to look up the slave instance and do specific setup.
Also will probably need code in the specific crtcs as dual-dsi
does not equal two separate dsi outputs.
To activate, the implementation-specific code should set the slave
using dw_mipi_dsi_set_slave() before calling __dw_mipi_dsi_bind().
v2:
- expect real interface number of lanes
- keep links to both master and slave
v3:
- remove unneeded separate variables
- remove unneeded second slave settings
- disable slave before master
- lane-sum calculation comments
