spi: Fix off-by-one error in calculating cycles per data frame
Issue: Configuring the frame length to certain values causes incorrect
operation.
Symptoms: Certain frame lengths result in the master sending one extra
clock pulse. The slave device may then become desynchronized.
Workaround: The following frame lengths are supported and can be used.
Do not use other frame lengths.
* Serial mode: 0, 2, 4, 6, 8
* Dual mode: 0, 1, 3, 5, 7, 8
* Quad mode: 0, 1, 2, 3, 5, 6, 7, 8

spi: Fix io.port.dq(3) output enable
Issue: The output enable signal for DQ[3] is not driven properly.
Symptoms: Output data from master to slave is not properly transmitted
in quad mode. Data received from the slave is unaffected.
Workaround: When interfacing with SPI flash devices, do not use the
"Quad Input/Output Fast Read" command (opcode 0xEB) while in the
Extended SPI protocol. Do not use the Native Quad SPI protocol.

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.

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

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!
