This patch series adds support for supporting multiple root 
DPRCs, which is an item on the TODO list. (This situation can
is possible when assigning multiple DPRCs to KVM virtual machines.)

Patch 1 abstracts the test for existence of an fsl-mc bus instance
into a function.

Patch 2 abstracts the test for whether a dprc is a root dprc 
into a function.

Patch 3 replaces use of the dev_root field in the bus type
struct to identify the root dprc with a more flexible
pointer traversal mechanism.

Patch 4 adds a counter to track the number of root dprcs.

Patch 5 removes all references to the now unused dev_root
