Subject: [PATCH] spi: Eliminate 3WIRE spi_transfer check

Checking for SPI_3WIRE isn't needed.  spi_setup() already prevents 3WIRE
mode from being combined with DUAL or QUAD mode support.  So there is no
need to differentiate between a single bit device with SPI_3WIRE set and
one with without.  It doesn't change the allowed bit widths.
