build/xilinx: add disable_constraints parameter to Platform.add_ip.

When integrate .xci, we don't necessarily want to apply the default timing/loc
constrants generated by Vivado but our custom ones. Setting disable_constraints
to True allow disabling .xdc generated by the IP.

bios/sdram: Use an LFSR to speed up pseudo-random number generation
...
This speeds up the memory test by an order of magnitude, esp. on
cores without a hardware multiplier by getting rid of the
multiplication in the loop.
The LFSR implementation comes from microwatt's simple_random test
project.

build/xilinx/vivado: ensure Vivado process our .xdc early.
...
When generating the LitePCIe PHY wrappers from the .xci, Vivado is locking the
PCIe lanes to default locations that do not necessarily match the ones used in
the design.
Processing our constraints earlier makes Vivado use our constraints and not the
ones from the generated wrapper.
