Subject: [PATCH 11/17] arm/samsung: Change s3c_pm_run_res() to use System RAM type

From: Toshi Kani <toshi.kani@....com>

Change s3c_pm_run_res() to check with IORESOURCE_SYSTEM_RAM, instead of
strcmp() with "System RAM", to walk through System RAM ranges in the
iomem table.

No functional change is made to the interface.
