There's a flags field on MMC host platform stuff that lets you describe
what the host controller can handle, for example 4-bit or high speed
etc. Adding a flag there that comes somehow from mach-gta02.c will
leave everyone else as they are.
I agree though in this case we are meddling with platform code and need
to take some care.
