[RFT PATCH] ia64: bigsur_defconfig: convert to use libata PATA drivers

[Bartlomiej Zolnierkiewicz]

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 bigsur_defconfig to use libata PATA
drivers.

    If you're enabling the MPIIX support (which I doubt is necessary), why not 
enable the "old" PIIX support?

I also doubt that it is necessary but IDE's piix host driver
includes support for it (so after conversion MPIIX is also
enabled).

Oversight on my side, will fix.

    MPIIX was for laptops only, IIUC.

Hi,

I'm running kernels configured that way (i.e. using libata PATA
drivers) for years on my hp workstation zx6000 (zx1 chipset) without
apparent problems.

Do you have PATA drives?  My zx6000 just has SCSI:

  scsi host0: ioc0: LSI53C1030 C0, FwRev=01032341h, Ports=1, MaxQ=255, IRQ=57

  scsi target0:0:0: FAST-160 WIDE SCSI 320.0 MB/s DT IU QAS RTI WRFLOW PCOMP (6.25 ns, offset 127)

[Wow! 36.4GB ... seemed like an OK sized drive back when that machine arrived in my lab. Now
 my phone has more than twice that amount of storage :-) ]
