[LEDE-DEV] [PATCH mountd] filesystem mount options in uci config

[olivier.hardouin at gmail.com]

Move (previously hardcoded) mount option to UCI to allow different configuration 
like charset (utf-8 or iso) and filesystem driver (if alternative ones are used).
The fs names are changed in lowercase to comply with UCI general naming.
