staging: fsl-mc: Added serialization to mc_send_command()
When the same portal is used to call mc_send_command() from two
different threads or a thread and an interrupt handler, serialization
is required, as the MC only supports one outstanding command per MC
portal. Thus, a new command should not be sent to the MC until the
last command sent has been responded by the MC.

staging: fsl-mc: Changed types of flags, portal size in
Changed these two fields from 32-bit integers to 16-bit integers in
struct fsl_mc_io, as 32 bits is too much for these fields. This
change does not affect other components since fsl_mc_io is an opaque

Before, we were opening and closing a mc_io's dpmcp object
in fsl_mc_portal_reset(), since that was the only function that was
calling dpmcp MC operations. However, it is better for maintainability
to open the dpmcp object when it gets associated with an mc_io object,
and close it when this association is terminated. This way, we are free
to call dpmcp operations on a mc_io's dpmcp object at any time, without
having to check if the dpmcp object is opened or not.
Consequently, the creation/teardown of the association between
an mc_io object and a dpmcp is now encapsulated in two functions:
fsl_mc_io_set_dpmcp()/fsl_mc_io_unset_dpmcp(). Besides, setting
the corresponding pointers for the association, these functions
open and close the dpmcp object respectively.

staging: fsl-mc: fsl_mc_io object refactoring
Each fsl_mc_io object is associated with an fsl_mc_device object
of type "dpmcp" representing the MC portal associated with the
fsl_mc_io object. Before, we were representing this association with
an fsl_mc_resource pointer. To enhance code clarity, it is more
straight forward to use an fsl_mc_device pointer instead.
So, this change replaces the 'resource' field in the fsl_mc_io
object with 'dpmcp_dev'. Also, it changes parameter 'resource' of
fsl_create_mc_io() to be an fsl_mc_device pointer instead.
