staging: vc04_services: Move global g_state to vchiq_state
The patch intended to drop the g_state pointer.
g_state is supposed to be a central place to track the state
via vchiq_state. This is now moved to be contained in the
struct vchiq_drv_mgmt. As a result vchiq_get_state() is also removed.
In order to have access to vchiq_drv_mgmt, vchiq_initialise()
and vchiq_mmal_init() are modified to receive a struct device pointer
as one of their function parameter
The vchiq_state pointer is now passed directly to
vchiq_dump_platform_instances() to get access to the state instead
getting it via vchiq_get_state().
For the char device, struct miscdevice is retrieved by struct file's
private data in vchiq_open and struct vchiq_drv_mgmt is retrieved
thereafter.
Removal of global variable members is now addressed hence, drop
the corresponding item from the TODO list.
