Even though it should never happen, handle the case that the clock
notifier is called with an unexpected clock handle. This avoids the
compiler warning:
drivers/staging/clocking-wizard/clk-xlnx-clock-wizard.c: In function 'clk_wzrd_clk_notifier':
>> drivers/staging/clocking-wizard/clk-xlnx-clock-wizard.c:99:6: warning: 'max' may be used uninitialized in this function [-Wmaybe-uninitialized]
if (ndata->new_rate > max)

The clk_name gets the return value from kasprintf (part of which does the
allocation of the returned buffer). So check the return pointer
before using it for clk_register_fixed_factor.

A macro doing some arithmetic to calculate a register offset, did not
contain an argument to the macro in parentheses, potentially leading to
unexpected results when using that macro with arithmetic expressions as
argument.

Add a driver for the Xilinx Clocking Wizard soft IP. The clocking wizard
provides an AXI interface to dynamically reconfigure the clocking
resources of Xilinx FPGAs.
