MIPS: Alchemy: Remove duplicate initializer

We get a harmless warning about a duplicate initalizer for the
i2c board info structure:

arch/mips/alchemy/board-gpr.c:239:11: error: initialized field overwritten [-Werror=override-init]

As both initializers have the identical value, we can simply drop
the second one.
