spi: rspi: Increase bit rate range for QSPI
Increase bit rate range for QSPI by extending the range of supported
dividers:
1. QSPI supports a divider of 1, by setting SPBR to zero, increasing
the upper limit from 48.75 to 97.5 MHz on R-Car Gen2,
2. Make use of the Bit Rate Frequency Division Setting field in
Command Registers, to decrease the lower limit from 191 to 24 kbps
on R-Car Gen2.
