drm: remove I2C_CLASS_DDC support

After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in
olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC.
Class-based device auto-detection is a legacy mechanism and shouldn't
be used in new code. So we can remove this class completely now.

drm/gma500: Remove unnecessary include statements for drm_crtc_helper.h

gma500: remove annoying deprecation warning

In commit e45708976aea ("drm/dp-helper: Move the legacy helpers to
gma500") the legacy i2c helpers were moved to the only remaining user of
them, the gma500 driver. Together with that move, i2c_dp_aux_add_bus()
was marked deprecated and started warning about its remaining use.

It's now been a year and a half of annoying warning, and apparently
nobody cares enough about gma500 to try to move it along to the more
modern models.

Get rid of the warning - if even the gma500 people don't care enough,
then they should certainly not spam other innocent developers with a
warning that might hide other, much more real issues.

drm/sysfs: sort out minor and connector device object lifetimes.

So drm was abusing device lifetimes, by having embedded device structures
in the minor and connector it meant that the lifetime of the internal drm
objects (drm_minor and drm_connector) were tied to the lifetime of the device
files in sysfs, so if something kept those files opened the current code
would kfree the objects and things would go downhill from there.

Now in reality there is no need for these lifetimes to be so intertwined,
especailly with hotplugging of devices where we wish to remove the sysfs
and userspace facing pieces before we can unwind the internal objects due
to open userspace files or mmaps, so split the objects out so the struct
device is no longer embedded and do what fbdev does and just allocate
and remove the sysfs inodes separately.
