spi: spi-mem: rtl-snand: Correctly handle DMA transfers
The RTL9300 has some limitations on the maximum DMA transfers possible.
For reads this is 2080 bytes (520*4) for writes this is 520 bytes. Deal
with this by splitting transfers into appropriately sized parts.
Fixes: 42d20a6a61b8 ("spi: spi-mem: Add Realtek SPI-NAND controller")
