Input: ads7846 - SPI_CPHA mode bugfix
In commit [1] the SPI mode is set to 1, but it should be 0. As stated
in the commit, ads784x samples the data on the rising edge. SPI mode 1
samples on the falling edge [2] though.
The root cause of this is a bug in the omap_uwire code, which treats
CPHA=1 incorrectly; so these two bugs cancel each other out on one
of the main regression test platforms for this driver.
