Move the panel specific VBT parsing to happen during the
output probing stage. Needs to be done because the VBT
parsing will need to look at the EDID to determine
the correct panel_type on some machines.
We split the parsed VBT data (i915->vbt) along the same
boundary. For the moment we just hoist all the panel
specific stuff into connector->panel.vbt since that seems
like the most convenient place for eg. the backlight code.
Note that we simply drop the drrs type check from
intel_drrs_frontbuffer_update() since that operates on the whole
device rather than a specific connector/encoder. But the check
was just a micro optimization so removing it doesn't actually
mattter for correctness.
TODO: Lot's of cleanup to be done in the future. Eg. most of
the DSI stuff could probably be eliminated entirely and just
parsed on demand during DSI init.
v2: Note the intel_drrs_frontbuffer_update() change

At least the Bay Trail LPSS PWM controller used with DSI panels on many
Bay Trail tablets seems to leave the PWM pin in whatever state it was
(high or low) ATM that the PWM gets disabled. Combined with some panels
not having a separate backlight-enable pin this leads to the backlight
sometimes staying on while it should not (when the pin was high during
PWM-disabling).
First calling intel_backlight_set_pwm_level() will ensure that the pin
is always low (or high for inverted brightness panels) since the passed
in duty-cycle is 0% (or 100%) when the PWM gets disabled fixing the
backlight sometimes staying on.
With the exception of ext_pwm_disable_backlight() all other
foo_disable_backlight() functions call intel_backlight_set_pwm_level()
already before disabling the backlight, so this change also aligns
ext_pwm_disable_backlight() with all the other disable() functions.
