spi: sh-msiof: Correct RX FIFO size for R-Car Gen2
According to Renesas Technical Updates TN-RCS-S068A/E, the MSIOF receive
FIFOs on R-Car Gen2 SoCs have room for 128 words of 32 bits.
Note that this change has no actual impact on the behavior of the
driver, as SPI_CONTROLLER_MUST_TX is set, and transfer size is currenty
limited to the minimum of the transmit and receive FIFO sizes.
