spi: a3700: Change SPI mode before asserting chip-select
The spi device mode should be configured in the controller before the
chip-select is asserted, so that a clock polarity configuration change
is not interpreted as a clock tick by the device.
This patch moves the mode setting to the 'prepare_message' function
instead of the 'transfer_one' function.
By doing so, this patch also removes redundant code in
a3700_spi_clock_set.
This was tested on EspressoBin board, with spidev.
