When CONFIG_DM_ETH is set, the FEC ethernet controller is reset after
the PHY has been set up and initialzed. This breaks the communication
with the PHY and results in an inoperable ethernet interface.

Do the initialization with CONFIG_DM_ETH in the same order as with
legacy ETH support to fix this.

i.MX 6UL and 6ULL have different boot device capabilities and
use therefor use a different boot device selection table than
other i.MX 6 devices. Particularly, the value which has been
used so far (b0001) is assigned to QSPI boot for these two
devices.

There is no common reserved value for all i.MX 6devices. Use
b0010 for i.MX 6UL and 6ULL via compile time ifdef.

DTB is encoded in big endian.  When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
mismatch.

We need to use (fdt32_t *) instead of (u32 *) for a pointer of a
property value.  Otherwise sparse warns "cast to restricted __be32".

This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing.  Follow the naming
of_get_property() from Linux.

The return type (const u32 *) is wrong.  DT property values can be
strings as well as integers.  This is why of_get_property/fdt_getprop
returns an opaque pointer.
