powerpc/85xx: Add support for FMan ethernet in Independent mode

The Frame Manager (FMan) on QorIQ SoCs with DPAA (datapath acceleration
architecture) is the ethernet contoller block.  Normally it is utilized
via Queue Manager (Qman) and Buffer Manager (Bman).  However for boot
usage the FMan supports a mode similar to QE or CPM ethernet collers
called Independent mode.

Additionally the FMan block supports multiple 1g and 10g interfaces as a
single entity in the system rather than each controller being managed
uniquely.  This means we have to initialize all of Fman regardless of
the number of interfaces we utilize.

Different SoCs support different combinations of the number of FMan as
well as the number of 1g & 10g interfaces support per Fman.

We add support for the following SoCs:
 * P1023 - 1 Fman, 2x1g
 * P4080 - 2 Fman, each Fman has 4x1g and 1x10g
 * P204x/P3041/P5020 - 1 Fman, 5x1g, 1x10g
