Add documentation in doc/drivel-model for the bind/unbind command.

As bind-test is now binded at sandbox startup and no more by
test_bind.py, bind-test nodes are not located at the end of
"dm tree" output, but can be located everywhere in the tree, so
bind-test output could either be:
sandbox: dts: Add compatible string for bind-test node
Usage of lists_bind_fdt() in bind command imposes to add
a compatible string for bind-test node.
Others impacts are:
- bind-test node is binded at sandbox start, so no need to bind it
in test_bind_unbind_with_node() test.
- As explained just above, after sandbox start, now a phy exist.
In test/dm/phy.c, it was verified that a third phy didn't exist,
now we must verified that a fourth phy doesn't exist.

Initial implementation invokes device_bind_with_driver_data()
with driver_data parameter equal to 0.
For driver with driver data, the bind command can't bind
correctly this driver or even worse causes data abort as shown below:
As example, for debug purpose on STM32MP1 platform, ethernet
(dwc_eth_qos.c) driver needed to be unbinded/binded.
This driver is using driver data:

New function should be called from board dram_init() because it initialized

On systems with multiple memory nodes finding out the first memory node by
fdtdec_setup_mem_size_base() is not enough because this memory can be above
actual U-Boot VA mapping. Currently only mapping till 39bit is supported
(Full 44bit mapping was removed by commit 7985cdf74b28 ("arm64: Remove
non-full-va map code")).
If DT starts with the first memory node above 39bit address then system can
be unpredictable.
The function is available only when multiple memory bank support is
enabled.
Calling fdtdec_setup_memory_banksize() from dram_init() is not possible
because fdtdec_setup_memory_banksize() is saving dram information to bd
structure which is placed on stack but not initialized at this time. Also

As is visible fdtfile was correctly composed but a null byte caused that
xlnx was separated from zynqmp.
This hasn't been spotted because in all Xilinx DTs there are at least 3

But for systems which only had one compatible string "xlnx,zynqmp" it was
