mtd: phram: Module parameters add writable permissions
The phram code implements managing multiple devices through a linked list. However, due to the module parameter permission of 0, the /sys/module/phram/parameters/phram interface is missing. The command line arguments in insmod can only create one device. Therefore, add writable permissions to the module parameters, create /sys/module/phram/parameters/phram interface, and create multi-device support.
