drm/kms: load fbcon from drm_kms_helper
Kconfig says fbcon is required by drm_kms_helper. If radeon, fbcon,
and drm_kms_helper are all modules, radeon is auto loaded (by PCI id?),
drm_kms_helper is loaded because of the module dependency, but fbcon
isn't loaded leaving the console unusable. Since fbcon is required
and there isn't an explicit module dependency, request the module
to be loaded from drm_kms_helper.

The workaround is to "echo 0 > /sys/bus/pci/devices/<device>/enable"
until the enable count reads 0. Then you should be able to load nouveau
with MSI enabled.

drm/nouveau: Refactor context destruction to avoid a lock ordering issue.
The destroy_context() engine hooks call gpuobj management functions to
release the channel resources, these functions use HARDIRQ-unsafe locks
whereas destroy_context() is called with the HARDIRQ-safe
context_switch_lock held, that's a lock ordering violation.
Push the engine-specific channel destruction logic into destroy_context()
and let the hardware-specific code lock and unlock when it's actually
needed. Change the engine destruction order to avoid a race in the small
gap between pgraph and pfifo context uninitialization.
