Checks for CONFIG_EXYNOS_ASV were added in v3.3. But the related Kconfig
symbol has never been added to the tree. Remove these checks, as they
always evaluate to false.

0) Untested.
1) I do not really care much for this patch. Two years is not very long
for dead code to remain in the tree. There is, however, a trivial issue
that makes this patch stand out from the other patches in my current
sweep of the tree for Kconfig related problems.
See, here the use of an unknown Kconfig macro hides an obvious typo: it
should either be "exynos_result_of_asv" or "exynos4_result_of_asv", but
not both. Ie, this almost certainly wouldn't have compiled even if the
Kconfig symbol EXYNOS_ASV would have been part of the tree.
2) So this makes me wonder whether there are any guidelines for using
Kconfig macros before the related Kconfig symbols are merged?
