[PATCH 00/20] drm/panel: Move to using mipi_dsi_*_multi() variants when available

[Anusha Srivatsa <asrivats@redhat.com>]

A lot of mipi API are deprecated and have a _multi() variant
which is the preferred way forward. This covers  TODO in the
gpu Documentation:[1]

An incomplete effort was made in the previous version
to address this[2]. It removed on the mipi_dsi_dcs_write_seq()
and mipi_dsi_generic_write_seq_multi() with the respective
replacemts and not the rest of the API.

The Coccinelle patch used to mkae changes:

expression list es;

static int jdi_write_dcdc_registers(struct jdi_panel *jdi)
