clk: clk-axi-clkgen: fix fpfd_max frequency for zynq
[ Upstream commit ce8a9096699500e2c5bca09dde27b16edda5f636 ] The fpfd_max frequency should be set to 450 MHz instead of 300 MHz. Well, it actually depends on the platform speed grade but we are being conservative for ultrascale so let's be consistent. In a following change we will set these limits at runtime.
