Now that we have added driver model support to the TSEC driver,
convert ls1021atwr board to use it.

This depends on previous DM series for ls1021atwr:

[Vladimir] Made the following changes:
- Added 'status = "disabled";' for all Ethernet ports in ls1021a.dtsi
- Fixed the confusion between the SGMII/TBI PCS for enet0 and enet1 -
  a mistake ported over from Linux. Each SGMII PCS lies on the private
  MDIO bus of the interface (and the RGMII enet2 has no SGMII PCS).
- Added CONFIG_DM_ETH to all ls1021atwr_* defconfigs
- Completely removed non-DM_ETH support from ls1021atwr
- Changed "compatible" string from "fsl,tsec-mdio" to "fsl,etsec2-mdio"
  and from "fsl,tsec" to "fsl,etsec2" to match Linux

In the case of the tsec network driver, so far there has been no
mainline user of DM_ETH where the DT bindings get used.

In the case of the mdio bus, it looks like the "fsl,tsec-mdio" string
was made up for the documentation, but there is no mainline code that
parses the "compatible" property anyway.

In both cases, there are no DT blobs that contain the old strings.

So change the documentation to "fsl,etsec2" for the Ethernet ports and
"fsl,etsec2-mdio" for the MDIO buses, which are strings that Linux also
uses, at least for LS1021A.  More compatible strings can be added once
other (PowerPC) SoCs are migrated to DM_ETH.

The current ls1021a.dtsi doesn't match what was documented for the MDIO
buses anyway (the "compatible" is "gianfar" currently). This will be
fixed in the next patch.

In tsec_init, the MAC address is retrieved from 2 different structures
depending on whether DM_ETH is enabled or not.

But since the field name is the same inside both structures, we can
conditionally define the structure of the correct type and simplify the
assignments.

By convention, the eTSEC MDIO controller nodes are defined in DT at
0x2d24000 and 0x2d50000, but actually U-Boot does not touch the
interrupt portion of the register map (MDIO_IEVENTM, MDIO_IMASKM,
MDIO_EMAPM).

That leaves only the MDIO bus registers (MDIO_MIIMCFG, MDIO_MIIMCOM,
MDIO_MIIMADD, MDIO_MIIMADD, MDIO_MIIMCON, MDIO_MIIMSTAT) which start at
the 0x520 offset.

So shift the DT-defined register map by the offset of MDIO_MIIMCFG when
mapping the MDIO bus registers.

Add support for A/B boot process on AM57xx based boards:

  1. Define 'slot_suffix' variable (using 'ab_select' command)
  2. Extend 'emmc_android_boot' boot command (add commands for A/B boot
     process)

'ab_select' command is used to decide which slot should be used for
booting up. A/B metadata resides in 'misc' partition.

To activate the A/B boot process, the following config options must be
set:

    CONFIG_ANDROID_AB=y
    CONFIG_CMD_AB_SELECT=y

For successful A/B boot, the corresponding A/B infrastructure must be
involved on Android side [1] (including mounting system as root), and
disk must be partitioned accordingly.

When A/B boot is enabled, there are some known limitations currently
exist (not related to A/B patches, need to be implemented later):

  1. The 'Verified Boot' sequence is not supported
  2. dev path to system partition (system_a or system_b) is passed via
     'bootargs' as 'root=' argument like 'root=/dev/mmcblk1p12', but
     further we'll need to rework it with respect to dm-verity
     requirements [2]

In case when A/B partitions are not present in system (and A/B boot is
enabled), boot up process will be terminated and next message will be
shown:

    "boot_a(b) partition not found"
