icside: use ide_init_port_hw()
* Move ide_find_port() and default_hwif_mmiops() calls from icside_setup() to icside_register_v{5,6}(). * Convert icside_setup() to initialize hw_regs_t instead ide_hwif_t and icside_register_v{5,6}() to use ide_init_port_hw(). * Rename icside_setup() to icside_setup_ports(). There should be no functional changes caused by this patch. Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
