Re: [U-Boot] [U-Boot, 8/8] rockchip: spi: make optimised receive-handler unaligned-safe

To support unaligned output buffers (i.e. 'in' in the terminology of the SPI framework), this change splits each 16bit FIFO element after reading and writes them to memory in two 8bit transactions. With this change, we can now always use the optimised mode for receive-only transcations independent on the alignment of the target buffer.

Given that we'll run with caches on, the impact should be negligible: as expected, this has no adverse impact on throughput if running with a 960MHz LPLL configuration.

Applied to u-boot-rockchip, thanks!
