CEC adapters and controllers (handlers) are now set up as follows:
1. Allocate CEC adapters: setup of control handlers in next step
requires these adapters to be allocated.
2. Setup of control handlers: This must be done prior to registering
and exposing the adapters to user space to avoid a race condition.
3. Register CEC adapters: make them available to user space.

The __packed macro isn't available in userspace with the kernel headers.
Checkpatch asks to use the macro, which is unwanted in a case of a UAPI
header. There is no much benefit in a tight packing of the structures,
hence let's pack them manually to cleanup things a tad. Note that there
is no old-stable userspace that will suffer from this change, hence it's
fine to change the ABI. In a result also more space is reserved for a
possible future expansion of the UAPI as it was already shown that more
fields will be needed for a later SoC generations.
