Subject: [PATCH 2/2] spi: atmel-quadspi: Remove duplicated DTR checks

Remove the DTR checks as they are already handled in
spi_mem_default_supports_op(). This code removal was intentionally not done
in the previous patch that introduced the use of the
spi_mem_default_supports_op() core helper and fixed the buswidth adjustment
between SPIMEM and the SPI controller, so that the fix can be easily
backported to stable kernels.
