common: Define three global clock nets

For all the Xilinx base design, define three global clock nets, which
are saved in the following three global variable: $sys_cpu_clk, $sys_dma_clk
and $sys_iodelay_clk.

These clock nets are connected to different clock sources depending of
the FPGA architecture used on the carrier. In general the following
frequencies are used:

  - sys_cpu_clk     - 100MHz
  - sys_dma_clk     - 200MHz or 250Mhz
  - sys_iodelay_clk - 200MHz or 500Mhz
