clk: ccf: mux: change the get_rate helper
The previous version of the get_rate helper does not work if the mux
clock parent is changed after the probe. This error has not been
detected because this condition has not been tested. The error occurs
because the set_parent helper does not change the parent of the clock
device but only the clock selection register. Since changing the parent
of a probed device can be tricky, the new version of the get_rate helper
provides the rate of the selected clock and not that of the parent.

clk: ccf: mux: fix access to the sandbox register
The tests developed for the mux clock are run on the sandbox. They don't
call the clk_mux_set_parent routine and therefore they do not detect
this error.
The top-level framework flags are passed as parameter to the common
clock framework (ccf) registration routines without being used.
Checks of the flags setting added by the patch have been added in the
ccf test.
dm: test: clk: add the test for the ccf gated clock
Unlike the other clock types, in the case of the gated clock, a new
driver has been developed which does not use the registering routine
provided by the common clock framework.
The addition of the ecspi0 clock to sandbox therefore allows testing
the ccf gate clock.

If DT starts with the first memory node above 39bit address then system can

The function is available only when multiple memory bank support is

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
causing an issue when U-Boot's DT was used by Linux kernel.
The patch removes strsep calling and strchr is called instead which just
locate the first char after deliminator ',' (variable called "name").
