Sergei Shtylyov d287223973 piix: fix 82371MX enablebits 
According to the datasheet, Intel 82371MX (MPIIX) actually has only a
single IDE channel mapped to the primary or secondary ports depending on
the value of the bit 14 of the IDETIM register at PCI config.  offset 0x6C
(the register at 0x6F which the driver refers to.  doesn't exist).  So,
disguise the controller as dual channel and set enablebits masks/values
such that only either primary or secondary channel is detected enabled. 
Also, preclude the IDE probing code from reading PCI BARs, this controller
just doesn't have them (it's not the separate PCI function like the other
PCI controllers), it only decodes the legacy addresses.

[ Alan sayeth " MPIIX does not work with or without the change.  It needs its
  own different driver and not to use setup-pci.  Huge job and since it works
  well with libata who cares.  Ditto the early PIIX chip." ]

* Errata of note:
*
* Unfixable
* PIIX4 errata #9 - Only on ultra obscure hw
* ICH3 errata #13 - Not observed to affect real hw
* by Intel
*
* Things we must deal with
* PIIX4 errata #10 - BM IDE hang with non UDMA
* (must stop/start dma to recover)
* 440MX errata #15 - As PIIX4 errata #10
* PIIX4 errata #15 - Must not read control registers
* during a PIO transfer
* 440MX errata #13 - As PIIX4 errata #15
* ICH2 errata #21 - DMA mode 0 doesn't work right
* ICH0/1 errata #55 - As ICH2 errata #21
* ICH2 spec c #9 - Extra operations needed to handle
* drive hotswap [NOT YET SUPPORTED]
* ICH2 spec c #20 - IDE PRD must not cross a 64K boundary
* and must be dword aligned
* ICH2 spec c #24 - UDMA mode 4,5 t85/86 should be 6ns not 3.3
*
* Should have been BIOS fixed:
* 450NX: errata #19 - DMA hangs on old 450NX
* 450NX: errata #20 - DMA hangs on old 450NX
* 450NX: errata #25 - Corruption with DMA on old 450NX
* ICH3 errata #15 - IDE deadlock under high load
* (BIOS must set dev 31 fn 0 bit 23)
* ICH3 errata #18 - Don't use native mode
