[9fans] teg2 kbd

does anyone know why the teg2 keyboard code has these two extra
scan code tables?

	case 5:
		*r = kbtabctrlesc1[*sc];
		return 1;
	case 6:
		*r = kbtabshiftesc1[*sc];
		return 1;

yep, that was for me.  weird uk usb keyboards.
nearly all the keyboard works but the pipe/backslash key is a special.
the patch appeared twice, once in the pc keyboard driver and once for the
raspberry pi (shared with omap).

there is also someone who had a similar problem with german keyboards
in the archives, though their fix was a little crude (sorry).

i worried at the time that adding two entire pages of lookup table seemed silly
to support one key with three functions, but memory is cheap enough that 2 x 256 bytes
is not outrageous. the 8042 is dead (ish)

would you mind submitting a 9atom patch?  since there where
5 conflicting versions of the scan code tables in the various kbd.c,
i think it got left behind.  the only copy of the scan codes is now
in port/devpckb.c.  so only two (nix and 9) files need updating.
