EISA: Drop unused pci_bus_for_each_resource() index argument

pci_bus_for_each_resource() can hide the iterator index if it is not needed
otherwise. Drop the index from pci_eisa_init() since it's not needed there.

EISA/PCI: Init EISA early, before PNP

Matthew reported kernels fail the pci_eisa probe and are later successful
with the virtual_eisa_root_init force probe without slot0.

The reason for that is: PNP probing is before pci_eisa_init gets called
as pci_eisa_init is called via pci_driver.

pnp 00:0f has 0xc80 - 0xc84 reserved.
[ 9.700409] pnp 00:0f: [io 0x0c80-0x0c84]

so eisa_probe will fail from pci_eisa_init
==>eisa_root_register
==>eisa_probe path.
as force_probe is not set in pci_eisa_root, it will bail early when
slot0 is not probed and initialized.

Try to use subsys_initcall_sync instead, and will keep following sequence:
pci_subsys_init
pci_eisa_init_early
pnpacpi_init/isapnp_init

After this patch EISA can be initialized properly, and PNP overlapping
resource will not be reserved.
[ 10.104434] system 00:0f: [io 0x0c80-0x0c84] could not be reserved

EISA/PCI: Fix bus res reference

Matthew found that 3.8.3 is having problems with an old (ancient)
PCI-to-EISA bridge, the Intel 82375. It worked with the 3.2 kernel.
He identified the 82375, but doesn't assign the struct resource *res
pointer inside the struct eisa_root_device, and panics.

pci_eisa_init() was using bus->resource[] directly instead of
pci_bus_resource_n(). The bus->resource[] array is a PCI-internal
implementation detail, and after commit 45ca9e97 (PCI: add helpers for
building PCI bus resource lists) and commit 0efd5aab (PCI: add struct
pci_host_bridge_window with CPU/bus address offset), bus->resource[] is not
used for PCI root buses any more.

The 82375 is a subtractive-decode PCI device, so handle it the same
way we handle PCI-PCI bridges in subtractive-decode mode in
pci_read_bridge_bases().

eisa/pci_eisa.c: fix BUG introduced by 005bdad7b80

While `pci_eisa_driver' still refer `pci_eisa_init', the .probe() function
should not be called after init memory release, as pointed out by commit
74b9a297. The structure is still referenced in the drivers subsystem, and can
be accesseed through sysfs, so the modpost warning is a false positive. Mark
it as such.

In the same time, the warning referenced in 005bdad7b80 did only mention
`pci_eisa_driver', not `pci_eisa_pci_tbl', so remove its marking.

eisa: remove driver_data direct access of struct device

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

[PATCH] drivers/eisa/pci_eisa.c:pci_eisa_init() should be init

WARNING: drivers/built-in.o - Section mismatch: reference to .init.text:eisa_root_register from .text between 'pci_eisa_init' (at offset 0xabf670) and 'virtual_eisa_release'

AFAIK a PCI to EISA bridge isn't anything hotpluggable, so
pci_eisa_init() can become __init.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
