Subject: [PATCH] linux-raspberrypi: change kernel cfg of drm from y to m to
 fix the pwm issue #1180

When I was trying to drive a lcd(ili9881) with pwm backlight control.
I encountered with the problem in #1180.
After I check the kernel config of both raspbian OS and yocto.I find
the config of drm is different between them.
Detail of difference:
In raspbian OS, kernel conifg of drm is m while it's y in yocto.

So I change the config of drm to m in yocto too.And the pwm works fine now.
