date bug

[Samuel Thibault]

Hello,

There used to be a bug that was making GNU Mach erroneously jump to year
2032 or something like that. In april 2021 I had committed

commit f040677be3c0eec63a5bd013a092ac5182790a50

    kd: Do not read the CMOS ram

    This could conflict with read/writing the RTC.

    * i386/i386at/kd.c (kd_xga_init): Do not read the CRAM. We were always
    assuming VGA anyway.

Did anybody notice the bug again since then? If not, we can probably
revert

    rtc: Add read/write messages

which was mostly to try to debug things a bit if the bug was still
there.
