ide: do not access ide_drive_t 'drive_data' field directly
Change ide_drive_t 'drive_data' field from 'unsigned int' type to 'void *'
type, allowing a wider range of values/types to be stored in this field.
Added 'ide_get_drivedata' and 'ide_set_drivedata' helpers to get and set
the 'drive_data' field.
Fixed all host drivers to maintain coherency with the change in the
'drive_data' field type.
