Subject: [PATCH] staging: iio: resolver: ad2s1210: Add explicit include for
 of.h

With linux/acpi.h no longer implicitly including of.h, add an explicit
include of of.h to fix the following error:

drivers/staging/iio/resolver/ad2s1210.c:706:21: error: implicit declaration of function 'of_match_ptr' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
