ramips: switched TP-Link RE305 v1 to new partition layout

Browse Source 
After trying to implement the gluon support for this device I ended up in a boot loop due to the usable amount of flash left. With this patch layout it uses the unused and empty flash space in the original partiton layout.
The version 3 of this device the RE365 share the same approach to have more usable space.
