Now that a device can be managed using the system blocks, a method to
reset the device is necessary as well. This patch introduces logic to
reset the device easily to factory state and exposes it through an
ioctl.
The ioctl takes the following flags:
NVM_FACTORY_ERASE_ONLY_USER
By default all blocks, except host-reserved blocks are erased upon
factory reset. Instead of this, only erase host-reserved blocks.
NVM_FACTORY_RESET_HOST_BLKS
Mark host-reserved blocks to be erased and set their type to free.
NVM_FACTORY_RESET_GRWN_BBLKS
Mark "grown bad blocks" to be erased and set their type to free.
