drm/panel: simple: Add missing Innolux G121X1-L03 format, flags, connector

[ Upstream commit 11ac72d033b9f577e8ba0c7a41d1c312bb232593 ]

The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ,
add the missing bus_format. Add missing connector type and bus_flags
as well.

Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is
capable of both RGB 18bit/24bit panel, the current configuration uses
18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6.

Support for the 24bit mode would require another entry in panel-simple
with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which
is out of scope of this fix.
