[PATCH] counter: fix ftm-quaddec build error on UML

[PATCH] counter: fix ftm-quaddec build error on UML

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Fix build error on user-mode Linux, which does not set HAS_IOMEM,
so devm_ioremap() is not available.  Fixes this build error:

ERROR: "devm_ioremap" [drivers/counter/ftm-quaddec.ko] undefined!

Fixes: a3b9a99980d9 ("counter: add FlexTimer Module Quadrature decoder counter driver")

Yes, commit 0c75376fa395 ("counter/ftm-quaddec: Add missing dependencies
in Kconfig") in Greg KH's staging repository in the staging-linus
branch should address this issue.
