spi: fsl: fix use of spisel_boot signal on MPC8309
Commit 0f0581b24bd0 ("spi: fsl: Convert to use CS GPIO descriptors")
broke the use of the SPISEL_BOOT signal as a chip select on the
MPC8309.
pdata->max_chipselect, which becomes master->num_chipselect, must be
initialized to take into account the possibility that there's one more
chip select in use than the number of GPIO chip selects.
