9985bdb1ce spi: kirkwood_spi.c: Add driver model support
This patch adds driver model support to the kirkwood SPI driver. Which
is also used on the MVEBU SoC's, now being converted to DM. Non-DM
support is still available for the "older" platforms using this
driver, like kirkwood.

04a44d3671 spi: zynq_qspi: Add configuration to disable LQSPI feature
When the Zynq Boot ROM code loads the payload from QSPI it uses the
LQSPI feature of the QSPI device, however it does not clean up its
configuration before handing over to the payload which leaves the device
confgured to by-pass the standard non-linear operating mode.

This ensures the Linear QSPI mode is disabled before re-enabling the
device.
