[PATCH] Subject: fbdev: sstfb: Make CONFIG_FB_DEVICE optional

[Gonzalo Silvalde Blanco]

The sstfb driver currently depends on CONFIG_FB_DEVICE to create sysfs
entries and access info->dev. This patch wraps the relevant code blocks
with #ifdef CONFIG_FB_DEVICE, allowing the driver to be built and used
even if CONFIG_FB_DEVICE is not selected.

Tested by building with and without CONFIG_FB_DEVICE, both of which
compile without issues
