linux-raspberrypi: change kernel cfg of drm from y to m to fix the pw…

…m 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.
