Subject: [PATCH] falconide: fix resources reservation (take 2)

* Tell IDE layer to not manage resources by setting
hwif->mmio flag and request resources in falconide_init().

* Use request_mem_region() for resources reservation.

* Use driver name for resources reservation.

v2:
* Fix missing printk() parameter. (Noticed by Geert Uytterhoeven)
