mfd: Fix ACPI conflict check

The code is currently always checking the first resource of every
device only (several times.) This has been broken since the ACPI check
was added in February 2010 in commit
f70b3c781642b84bd36aed8903804fe04fae1676.

Fix the check to run on each resource individually, once.
