ide: define MAX_HWIFS in <linux/ide.h>
* Now that ide_hwif_t instances are allocated dynamically
the difference between MAX_HWIFS == 2 and MAX_HWIFS == 10
is ~100 bytes (x86-32) so use MAX_HWIFS == 10 on all archs
except these ones that use MAX_HWIFS == 1.
* Define MAX_HWIFS in <linux/ide.h> instead of <asm/ide.h>.
[ Please note that avr32/cris/v850 have no <asm/ide.h>
and alpha/ia64/sh always define CONFIG_IDE_MAX_HWIFS. ]
