spi: sun4i: update max transfer size reported
The spi-sun4i driver already has the ability to do large transfers.
However, the max transfer size reported is still fifo depth - 1.
Update the max transfer size reported to the max value possible.
Fixes: 196737912da5 ("spi: sun4i: Allow transfers larger than FIFO size")
