Subject: [RFT PATCH] mips: lemote2f_defconfig: convert to use libata PATA
 drivers

IDE subsystem has been deprecated since 2009 and the majority
(if not all) of Linux distributions have switched to use
libata for ATA support exclusively.  However there are still
some users (mostly old or/and embedded non-x86 systems) that
have not converted from using IDE subsystem to libata PATA
drivers.  This doesn't seem to be good thing in the long-term
for Linux as while there is less and less PATA systems left
in use:

* testing efforts are divided between two subsystems

* having duplicate drivers for same hardware confuses users

This patch converts lemote2f_defconfig to use libata PATA
drivers.

PS This platform uses CS5536 chipset which (due to historical
reasons) has basic support in AMD/nVidia PATA host driver and
full support in a newer CS5536 PATA one (pata_cs5536).  Thus
most likely this platform should switch to using the latter
host driver.
