FATFS support without wear levelling
This change allows readonly FATFS to be mounted without wear levelling support. This will provide the customers a simple way to mount FATFS images generated on host and flashed onto the chip during factory provisioning. Since NVS encryption is not supported yet and NVS entry size is limited, the change will provide an easy alternative for securing the provisioning data by just marking FATFS parition as encrypted.
