"Fix" false combinational loop through SPIArbiter
...
Mux1H converts aggregates to UInt, muxes, then converts back which can
look like a cominational loop.

Use HomogenousBag to handle lists of peripherals
...
Previously we had to do weird things to make non-homogenous
lists of items (e.g. PWM Peripherals where ncmp were different from one to
the other) into a vector. But now Chisel supports a Record type,
and we use the HomogenousBag utility to do this more naturally.
This also deletes all the cruft which was introduced to get
around the limitation which doesn't exist anymore.

xilinx pcie: bytes, not bits
...
This bug amazingly compiled correctly and ran correctly!
It was saved by the AXIFragmenter which turned the "narrow burst" into
individual beats that then got converted to 64b in TileLink land via
inspection of the mask bits.
The consequence is that AXI bus mastering proceeded at one word per
DDR round-trip. Now it is one cache line per DDR round-trip. When we
get L2 back in the design, it should really fly!
