Subject: [PATCH 0/2] spi: ar934x: fix transfer size and delays

Some of slow SPI devices can not handle 32 bits transfers or need
delay between words/transfers.

Series is tested with ATSAMD20J15 slave device which is running @8Mhz.
Limiting bits per word to 16 bits and adding delay between transfers,
gives slave device enough extra time to process reply.
