struct pcmcia_device *p_dev->conf.ConfigBase and .Present are set in almost
all PCMICA driver right at the beginning, using the same calls but slightly
different implementations. Unfiy this in the PCMCIA core.

As we read out the product information strings (VERS_1) from the PCMCIA device
in the PCMCIA core, and device drivers can access those reliably in struct
pcmcia_device's fields prod_id[], remove additional product information string
detection logic from PCMCIA device drivers.

As we read out the manufactor and card_id from the PCMCIA device in the

s->functions needs to be initialized earlier, for the "let's see
how high it increases" approach means that pcmcia_request_irq()
(which makes use of this value) is confused, and might request
an exclusive IRQ first even though it is not supposed to.
Also, a CIS override autoloaded using the firmware loader may
allow for the use of more or less functions in a multifunction
card. Therefore, we may need to schedule a call to add this
second function later on, or simply remove the other function
(it's always the first -valid- function which reaches this
codepath).
Many thanks to Fabrice Bellet for debugging and testing patches.

Switch to pci_get_bus_and_slot because some x86 systems seem to be
handing us a device with dev->bus = NULL. Also don't apply the isa fixup
to revision C6 and later of the chip.
Really we need to work out wtf is handing us pdev->bus = NULL, but firstly
and more importantly we need the drivers working.
