This driver uses devm_spi_register_master() so don't explicitly call
spi_master_put() in spi_qup_remove().

Set master->max_speed_hz then spi core will handle checking transfer speed.
So we can remove the same checking in this driver.
Also remove checking spi->chip_select in spi_qup_setup(), the checking is done
by spi core.

Just found the subject line is wrong...
Should be spi:qup rather than spi:dup.
I'm going to resend this patch serial.
