[PATCH 01/28] sh-pfc: Fix compiler warning when BUG()

[Simon Horman]

From: Laurent Pinchart <laurent.pinchart+renesas at ideasonboard.com>

The sh_pfc_phys_to_virt() function ends with a BUG() statement without a
return. When CONFIG_BUG isn't set the function will thus have no return
value. Fix it.
