adc: ADS7052 correct spi configuration

teburd · MaureenHelm · commit da5030eae10d · 2023-05-03T08:46:37.000-05:00
SPI configuration did not set bit ordering or more importantly the clock
polarity which seemed to be misconfigured. Setting this corrects one more
quirk when working with this part on the TDK Robokit1
