This fragment of drivers/firmware/pcdp.c should move to the
IA64_EARLY_PRINTK_UART patch.

With "console=uart,io,0x3f8" or similar, a serial console
works early enough for most things (not *quite* as early as
IA64_EARLY_PRINTK_UART admittedly).

ia64: remove HCDP support for early printk

This is only used by the ia64 early_printk patch, which isn't in the
mainline tree.  If anybody is still using that patch, hcdp_early_uart()
should be incorporated into it.
