[PATCH] drm: drm_drv: Only call drm_agp_clear() in __OS_HAS_AGP case

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

Commit 28ec711 (drm/agp: move AGP cleanup paths to drm_agpsupport.c) causes the 
following link error on ARM (imx_v6_v7_defconfig):

drivers/built-in.o: In function `drm_lastclose':
:(.text+0x588a0): undefined reference to `drm_agp_clear'
make: *** [vmlinux] Error 1

drm_agp_clear() is defined only '#if __OS_HAS_AGP' is true, so add this 'if'
logic when calling it.
