cores/prbs: Add a 'wrap' option to PRBSRX
...
If enabled, then the error count wraps around when it
reaches the limit of the 32b counter instead of saturating
to a max value.
Software can then detect the wrap and act accordingly.

soc/cores/led/WS2812: Add Bus Mastering capability.
...
Useful on small FPGAs to reduce resource usage: When enabling bus mastering,
the core is able to automatically read led values from the bus and can then
avoid the internal memory. This is particularly useful when reading values
from SPI Flash with a small "Player" core just updating the base address.

Add `reg-names` property, which facilitates cleaner probing
for the upstream Linux device driver. Also, add a reference
to the LiteX sys_clk, also for the benefit of the upstream
driver, which can't rely on the CPU frequency matching sys_clk.
