drm/vkms: Add vkms_config type

Browse Source 
Currently, data for the device instance is held by vkms_device.
Add a separate type, vkms_config to contain configuration details
for the device and various modes to be later used by configfs.
This config data stays constant once the device is created.

Accordingly, add vkms_create and vkms_destroy to initialize/destroy
device through configfs. Currently, they are being called from vkms_init
and vkms_exit, but will be evoked from configfs later on. When configfs
is added, device configuration will be tracked by configfs and only vkms
device lifetime will be handled by vkms_init and vkms_exit functions.

Modify usage of enable_cursor feature to reflect the changes in
relevant files.
