fbdev: pxa168fb: use devm_ioremap_resource() for MMIO

Browse Source 
pxa168fb maps the LCD controller register resource with devm_ioremap(),
which does not request the memory region. Use devm_ioremap_resource()
instead so the MMIO range is claimed before being mapped.

This also handles cleanup automatically.
