spi: dw: rename the spi controller to ctlr
Since the designware SPI controller can act as both a target and a host,
rename spi_controller member of the dw_spi struct to ctlr instead of host.
Similarly, rename the functions handling the controller, using controller
instead of host as the suffix.
No functional changes intended.
