Subject: ARM: OMAP2+: Remove unused legacy code for watchdog
X-Git-Tag: v4.13-rc1~169^2~12^2~5^2~1

ARM: OMAP2+: Remove unused legacy code for watchdog

We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.
