Its not a dependency, just a default (presumably so that existing
kernel configs get updated automatically).

Note that sead3 now uses MIPS_GENERIC (or more specifically
CONFIG_LEGACY_BOARD_SEAD3), but this driver is enabled in the config
snippets, e.g.:
arch/mips/configs/generic/board-sead-3.config
arch/mips/configs/generic/board-boston.config

so indeed there is no real need to replace MIPS_SEAD3 with anything here.

Cheers
James
