spi: bcm2835: move to the transfer_one driver model
This also allows for GPIO-CS to get used removing the limitation of 2/3 SPI devises on the SPI bus. Fixes: spi-cs-high with native CS with multiple devices on the spi-bus resetting the chip selects to "normal" polarity after a finished transfer. No other functionality/improvements added. Tested with the following 4 devices on the spi-bus: * mcp2515 with native CS * mcp2515 with gpio CS * fb_st7735r with native CS (plus spi-cs-high via transistor inverting polarity) * enc28j60 with gpio-CS Tested-by: Martin Sperl <kernel@martin.sperl.org> Signed-off-by: Martin Sperl <kernel@martin.sperl.org> Signed-off-by: Mark Brown <broonie@kernel.org>
