Subject: [PATCH 00/22] VKMS: Introduce multiple configFS attributes

VKMS have a wide range of options. The aim of this series is to introduce
many configfs attribute so VKMS can be used to test a wide range of
configurations.

This series depends on [1] that should be applied soon.

PATCH 1-13 are for configuring planes
- name
- rotation
- color encoding
- color range
- plane formats
- zpos
PATCH 14-19 are for configuring the connector
- type
- supported colorspace
- edid
PATCH 20-22 are to enable dynamic connectors

PS: Each pair of config/configfs patch are independant. I could
technically create ≈10 different series, but there will be a lot of
(trivial) conflicts between them. I will be happy to reordoer, split and
partially apply this series to help the review process.
