m68k/mac: Disentangle VIA and OSS initialization
macintosh_config->via_type is meaningless on Mac IIfx (i.e. the only
model with OSS chip), so skip the via_type switch statement.
Call oss_init() before via_init() because it is more important and
because that is the right place to initialize the oss_present flag.
On this model, bringing forward oss_init() and delaying via_init()
is no problem because those functions are independent.
The only requirement here is that oss_register_interrupts() happens
after via_init(). That is, mac_init_IRQ() happens after config_mac().
