I don't really like using such string based conditions in the code, but I
guess it's just a matter of preference.

I'd introduce an enum to represent supported variants and put them into
the OF match table or maybe even a struct that would have a bool named
has_adma_clock, true for Exynos5420 variant.

Best regards,
Tomasz
