The Meson SPICC is generic SPI controller for general purpose Full-Duplex
communications with dedicated 16 words RX/TX PIO FIFOs.
It differs completely from the SPIFC, and thus need a separate driver.

The current driver only supportd the PIO transfer mode since the DMA seems
broken on available hardware.

This driver has been tested on a Amlogic S905X board.
