drivers/spi: Re-factor spi_crop_chunk
spi_crop_chunk is a property of the SPI controller since it depends upon the maximum transfer size that is supported by the controller. Also, it is possible to implement this within spi-generic layer by obtaining following parameters from the controller: 1. max_xfer_size: Maximum transfer size supported by the controller (Size of 0 indicates invalid size, and unlimited transfer size is indicated by UINT32_MAX.) 2. deduct_cmd_len: Whether cmd_len needs to be deducted from the max_xfer_size to determine max data size that can be transferred. (This is used by the amd boards.)
