* use kernel buildin transfer_one_message. we only need to implement
transfer_one and set_cs function
* should support use gpio as cs pin
* deselected the spi device when setup and add debug info
* only reset device when first driver probe

before spi transfer. use spi_prepare_message to setup spi hardware. it
will setup MSB, spi mode and speed
remove sys_freq member and speed check code

* fill struct according to the member order
* add error clean up
* set min/max spi speed. so we don't need to check again

use loops_per_jiffy, spi clock speed and write bytes to get the
spi loop count. if loop to 0 than spi operation timeout.
remove usleep. we only write 1 byte to spi device. use busy loop
would be better.
