Remove sio(4) and related options from MI files to amd64, i386

and pc98 MD files. Remove nodevice and nooption lines specific
to sio(4) from ia64, powerpc and sparc64 NOTES. There were no
such lines for arm yet.
sio(4) is usable on less than half the platforms, not counting
a future mips platform. Its presence in MI files is therefore
increasingly becoming a burden.

 # MISCELLANEOUS DEVICES AND OPTIONS

+hint.sio.0.irq="4"
+
+# `flags' specific to sio(4).
+#	0x10	enable console support for this unit.  Other console flags
+#		(if applicable) are ignored unless this is set.  Enabling
+#		console support does not make the unit the preferred console.
+#		Boot with -h or set boot_serial=YES in the loader.  For sio(4)
+#		specifically, the 0x20 flag can also be set (see above).
+#		Currently, at most one unit can have console support; the
+#		first one (in config file order) with this flag set is
+#		preferred.  Setting this flag for sio0 gives the old behaviour.
+#	0x20	force this unit to be the console (unless there is another
+#		higher priority console).  This replaces the COMCONSOLE option.
+#	0x40	reserve this unit for low level console operations.  Do not
+#		access the device in any normal way.
+#	0x80	use this port for serial line gdb support in ddb.  Also known
+#		as debug port.
+# PnP `flags'
+#	0x1	disable probing of this device.  Used to prevent your modem
+#		from being attached as a PnP modem.
+# Other flags for sio that aren't documented in the man page.
+#	0x20000	enable hardware RTS/CTS and larger FIFOs.  Only works for
+#		ST16650A-compatible UARTs.
+
+# Options for sio:
+options 	COM_ESP			# Code for Hayes ESP.
+options 	COM_MULTIPORT		# Code for some cards with shared IRQs.
+options 	CONSPEED=115200		# Speed for serial console
+					# (default 9600).
