Make of_device_id array const, because all OF functions
handle it as const.

Current code uses struct spi_qup_device to store spi->mode and spi->chip_select
settings. We can get these settings in spi_qup_transfer_one and spi_qup_set_cs
without using struct spi_qup_device. Refactor the code a bit to remove
spi_qup_setup(), spi_qup_cleanup(), and struct spi_qup_device.

The module version is unlikely to be updated, use kernel version should be
enough.

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.

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

Qualcomm Universal Peripheral (QUP) core is an AHB slave that
provides a common data path (an output FIFO and an input FIFO)
for serial peripheral interface (SPI) mini-core. SPI in master
mode supports up to 50MHz, up to four chip selects, programmable
data path from 4 bits to 32 bits and numerous protocol variants.
