HAVE_XORG_SERVER_VER settings

[Izumi Tsutsui <tsutsui%ceres.dti.ne.jp@localhost>]

Currently bsd.own.mk has the following list to switch Xorg versions:

---
# During transition from xorg-server 1.10 to 1.20
.if \
    ${MACHINE} == "alpha"       || \
    ${MACHINE} == "amiga"       || \
    ${MACHINE} == "ews4800mips" || \
    ${MACHINE} == "hpcarm"      || \
    ${MACHINE} == "hpcmips"     || \
    ${MACHINE} == "hpcsh"       || \
    ${MACHINE} == "mac68k"      || \
    ${MACHINE} == "netwinder"   || \
    ${MACHINE} == "newsmips"    || \
    ${MACHINE} == "sgimips"     || \
    ${MACHINE} == "vax"         || \
    ${MACHINE} == "x68k"        || \
    ${MACHINE} == "zaurus"
HAVE_XORG_SERVER_VER?=110
.else
HAVE_XORG_SERVER_VER?=120
.endif

Is there any reason to stick on 1.10.6 for ports that just use
MI wscons drivers like xf86-video-wsfb and xf86-input-keyboard etc.?
(at least ews4800mips, hpcarm, hpcmips, hpcsh, newsmips, and zaurus)

dreamcast (16bpp) and luna68k (1bpp) are somehow missed in the
above list but they just work fine with 1.20.
