video: panel: renesas-r69328: use common mipi_dsi_dcs_write_seq macro

The current driver defines dsi_generic_write_seq as a wrapper around
mipi_dsi_dcs_write_buffer.

Now that mipi_dsi.h defines such macro, we can use the common one.
Note that we use mipi_dsi_dcs_write_seq instead of
mipi_dsi_generic_write_seq to keep the same behaviour.

While at it also use mipi_dsi_dcs_write_seq instead of direct call to
mipi_dsi_dcs_write_buffer for address_mode, and remove static
address_mode variable.

No functional changes intended.
