we've been trying to get rid of the legacy ide driver for a while now,
and finally scheduled a removal for 2021, which is three month old now.
In general distros and most defconfigs have switched to libata long ago,
but there are a few exceptions. This series first switches over all
remaining defconfigs to use libata and then removes the legacy ide
libata mostly covers all hardware supported by the legacy ide driver.
There are three mips drivers that are not supported, but the linux-mips
list could not identify any users of those. There also are two m68k
drivers that do not have libata equivalents, which might or might not
have users, so we'll need some input and possibly help from the m68k
