mtd: fsl_ifc_nand: Workaround bogus WP on 16-bit NAND
A workaround was already in place that set the WP bit in the IFC_CSPR0 register after a STATUS command, however it used an 8-bit write method. As a result, the WP bit was never set on 16-bit devices, and these devices would eventually be incorrectly marked as write-protected. This patch checks the chip options for a 16-bit device and uses the appropriate write method to set the WP bit after a STATUS command.
