spi: spi-fsl-lpspi: fix watermark truncation caused by type cast
't->len' is an unsigned integer, while 'watermark' and 'txfifosize' are
u8. Using min_t with typeof(watermark) forces both values to be cast to
u8, which truncates len when it exceeds 255. For example, len = 4096
becomes 0 after casting, resulting in an incorrect watermark value.
Use a wider type in min_t to avoid truncation and ensure the correct
minimum value is applied.
