spi: spi-fsl-lpspi: limit PRESCALE bit in TCR register

Referring to the errata ERR051608 of I.MX93, LPSPI TCR[PRESCALE]
can only be configured to be 0 or 1, other values are not valid
and will cause LPSPI to not work.

Add the prescale limitation for LPSPI in I.MX93. Other platforms
are not affected.
