(ofdisk_hash): New hash table.
(ofdisk_hash_fn, ofdisk_hash_find, ofdisk_hash_add): New functions.
(grub_ofdisk_open): Use ofdisk_hash_ent address as disk->id
instead of device phandle which is not unique.
slots are of type grub_ieee1275_cell_t.
(grub_nand_read): Likewise.
* kern/ieee1275/ieee1275.c (IEEE1275_PHANDLE_INVALID,
IEEE1275_IHANDLE_INVALID): Use grub_ieee1275_cell_t since these
macros are used to compare values in arg/ret block of the call.

grub_ieee1275_next_property, grub_ieee1275_get_property_length,

grub_ieee1275_close, grub_ieee1275_set_property,
grub_ieee1275_set_color): All ieee1275 call arg slots are of type
grub_ieee1275_cell_t.
* kern/ieee1275/openfw.c (grub_map): Likewise.
* include/grub/ieee1275/ieee1275.h (grub_ieee1275_ihandle_t,
grub_ieee1275_phandle_t): Define as grub_unit32_t type.
