Explicitly clear AUXIO4M_FTC bit in FTC_FLIP macro used on
pseudo-dma for floppy, as well as AUXIO4C_FTC bit for sun4c.
A comment in the macro says AUXIO4M_FTC bit is auto-clear,
but my two SS20s (including compatible) with 150MHz hyperSPARCs
get data_overrun without it, and no bad side effect on SS5
(works with and without this change).
Closes PR port-sparc/42516, which is the last one of a bunch of
floppy issue on NetBSD/sparc since NetBSD 2.0 days. See
