mmc: have mmc_align_data_size use ALIGN() macro

No sense manually doing the alignment dance, there's a macro for that. Once the optimal alignment stuff is added, this could probably turn into something like this (in core.h):

static inline u32 mmc_align_data_size(struct mmc_card *card, u32 sz)

{
	return ALIGN(sz, card->align_sz);
}

There are so many macros in those headers, it's impossible to keep track of them all. :/

I'm afraid you missed the main discussion, but the idea is to expand that function and make it depend on the particular bugs of the controller associated with the given card. I.e. it will not stay suitable for inlining very long.
