3038171628 powerpc/85xx: fix null pointer dereference when init the SGMII TBI PHY
Function dtsec_configure_serdes() needs to know where the TBI PHY registers
are in order to configure SGMII for proper SerDes operation.

During SGMII initialzation, fm_eth_init_mac() passing NULL for 'phyregs'
when it called init_dtsec(), because it was believed that phyregs was not
used.  In fact, it is used by dtsec_configure_serdes() to configure the TBI
PHY registers.

We also need to define the PHY registers in struct fm_mdio.

c916d7c914 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
