Random numbering of MGT_CLKREF
- MGT_CLKREF.CLK_4 comes from IC2 OUT0 and drives MGTC1, MGTC2
- MGT_CLKREF.CLK_1 comes from IC2 OUT1 and drives FMC MGTs
- MGT_CLKREF.CLK_0 comes from IC2 OUT2 and drives FMC MGTs
- MGT_CLKREF.CLK_3 comes from IC2 OUT3 and drives MGTC3..6
- MGT_CLKREF.CLK_2 comes from IC2 OUT4 and drives MGTC7..8
can we renumber them in a bit more logical sense? without changing routing of course, just net labels.
