mfd: 88pm860x: Use REG resource for backlight
Now resource of 88pm860x backlight is changed from IORESOURCE_IO to IORESOURCE_REG. In original driver, the resource is using self-defined IORESOURCE_IO. So change the resource to register offset to match the definition of IORESOURCE_REG. Signed-off-by: Haojian Zhuang <haojian.zhuang@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
