dwc3-generic: Don't fail probe if clk/reset entries are absent

Some boards don't populate clk/reset entries as these are are optional
as per binding documentation. Therefore, don't fail driver probe if
clk/reset entries are absent in DT.

This fixes fastboot failures seen due to enabling of CONFIG_CLK on AM57xx
