Subject: [PATCH] mfd: arizona: Correct handling of device tree gpio defaults

The intention is that all out of range values should cause the chips
default settings to be used and a value of zero should be treated
literally. Currently all out of range values will hit the second if and
be treated as a literal zero. This patch adds an else to fix this issue.
