[PATCH v2] drm/qxl: remove dependency on DRM simple helpers

[Diogo Silva <diogompaissilva@gmail.com>]

Simple KMS helper are deprecated since they only add an intermediate
layer between drivers and the atomic modesetting.
This patch removes the drm_simple_encoder_init() helper usage in the
qxl display driver by open coding it and using the encoder atomic
helpers directly. This is a step to eventually get rid of this simple
KMS helper, once all drivers that use it have been converted.
