[PATCH] spi: sun4i: update max transfer size reported

[Jonathan Liu]

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")
