firmware: xilinx: Move EXPORT_SYMBOL_GPL next to zynqmp_pm_feature definition

As mentioned in Documentation/process/coding-style.rst:
In source files, separate functions with one blank line. If the function
is exported, the **EXPORT** macro for it should follow immediately after
the closing function brace line.

So inline with guideline move zynqmp_pm_feature export symbol after its
definition.
