[PATCH] sh: crash kernel resource fix

[PATCH] sh: crash kernel resource fix

[Magnus Damm]

From: Magnus Damm <damm@igel.co.jp>

The reserved crash kernel memory range is currently missing from
/proc/iomem. crashk_res is mistakenly setup after __add_active_range().
Reorder things to make sure the resource shows up in /proc/iomem.

Applied, thanks.
