drm: Perform cmdline mode parsing during connector initialisation
i915.ko has a custom fbdev initialisation routine that aims to preserve
the current mode set by the BIOS, unless overruled by the user. The
user's wishes are determined by what, if any, mode is specified on the
command line (via the video= parameter). However, that command line mode
is first parsed by drm_fb_helper_initial_config() which is called after
i915.ko's custom initial_config() as a fallback method. So in order for
us to honour it, we need to move the cmdline parser earlier. If we
perform the connector cmdline parsing as soon as we initialise the
connector, that cmdline mode and forced status is then available even if
the fbdev helper is not compiled in or never called.
We also then expose the cmdline user mode in the connector mode lists.
v2: Rebase after connector->name upheaval.
v3: Adapt mga200 to look for the cmdline mode in the new place. Nicely
simplifies things while at that.
v4: Fix checkpatch.
v5: Select FB_CMDLINE to adapt to the changed fbdev patch.
