gx1fb: Fix section mismatch warnings

Fix a chain of section mismatches in geode driver, beginning with:

WARNING: drivers/video/geode/gx1fb.o(.data+0x70): Section mismatch in reference from the variable gx1fb_driver to the function .init.text:gx1fb_probe()
The variable gx1fb_driver references
the function __init gx1fb_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

Making the changes that Paul pointed out resulted in a few more
changes being needed, so they are all included here.
