c59356d1de spi: Fix invalid D channel response when flash interface is disabled 
Issue: When the memory-mapped flash region is accessed while the flash
read mode is disabled (fctrl.en flag is clear), the SPI flash controller
generates an invalid response on the D channel.
This may cause the TileLink bus to deadlock.

Workaround: Software should avoid accessing the memory-mapped flash
region when the SPI controller is not in the flash read mode.

75d6a7c6ea 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

eea10f5129 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.
