[PATCH] ARM: imx_v6_v7_defconfig: Enable CONFIG_PWM_IMX27

[Leonard Crestez]

Commit d80f8206905c ("pwm: imx: Split into two drivers") also adds a new
CONFIG_PWM_IMX27 for the PWM block on recent IMX chips and we should
enable it by default for imx.

Restoring the PWM driver fixes an infinite probe loop in 5.1-rc1 on
various imx6qdl-sabresd boards.

Probe loop repeats following lines:

Maybe it's an imx-drm bug which got exposed by accident?
