spi: sh-sci: Prevent NULL pointer dereference
If sp->info is NULL, we will hit NULL pointer dereference in probe() while
setting bus_num and num_chipselect for master:
sp->bitbang.master->bus_num = sp->info->bus_num;
sp->bitbang.master->num_chipselect = sp->info->num_chipselect;
Thus add NULL test for sp->info in probe() to prevent NULL pointer dereference.
