This controller is a superset of the already supported qca,ar7100-spi.
Besides the bit-bang mode in spi-ath79.c, this new controller added
a new "shift register" mode, allowing faster spi operations.
This mode doesn't need all the bit-bang code in spi-ath79.c and needs
a different clock setup, so I decided to write a new driver for it
instead of extending current spi-ath79 driver.

Change since v2:
fix binding documentation check.

Changes since v1:
1. change comment at the beginning to C++ style
2. rename ar934x_spi_transfer_one to ar934x_spi_transfer_one_message
