Add support for the AD-FMCDAQ2-EBZ on the Arria10 SoC development board platform.
In its default configuration the Arria10 SoC development board is not fully
compatible with the AD-FMCDAQ2-EBZ and a slight rework is necessary,
changing the position of four 0 Ohm resistors:
R610: DNI -> R0
R611: DNI -> R0
R612: R0 -> DNI
R613: R0 -> DNI
R620: DNI -> R0
R632: DNI -> R0
R621: R0 -> DNI
R633: R0 -> DNI

Rework the peripheral address to match the updated semantics of
ad_cpu_interconnect, which expects that the addresses are in the range of
0x00010000 - 0x001fffff. This includes updating the base addresses as well
as compressing the used address range to fit into the 2Mb window.

The DDR memory reference clock on the A10SoC development board is
differential. Currently the EMIF core it is configured for single-ended
configuration, which causes it to generate incorrect IOSTANDARD
constraints. Those incorrect constraints get overwritten again in
system_assign.tcl, so things are working, but this generates a warning when
building the design
Configure the EMIF core correctly and remove the manual constraint overwrite since
they are no longer necessary.

There is no guarantee that the external reset de-assertion is synchronous
to the sys_clk, yet the clock bridge marks the reset de-assertion as
synchronized to the clock. This can cause recovery or removal timing
violations for the registers affected by this reset signal and potentially
bring the system into an invalid state after the reset is de-asserted.
Mark the reset as not synchronized to the clock signal, this will make sure
that Qsys inserts the proper reset synchronizers where required.
