sunxi: Rename A10s-Wobo-i5_defconfig to Wobo_i5_defconfig

We only prefix the board defconfig name with the SoC if the SoC is part
of the official board-name, such as with Olimex OLinuxIno boards, for the
Wobo i5 this is not the case so remove the A10s prefix from the defconfig
filename.

Also fix the double listing of A10s-OLinuXino-M_defconfig in MAINTAINERS
which the original Wobo i5 addition commit introduced.
