Add pci_enable_device() to aec62xx probe function
before doing any I/O.
Original probe function tries to read from device's
PCI region 4 before calling ide_setup_pci_device().
Since the device is not enabled at this point,
on machines that have no firmware PCI initialization
(e.g. ASUS WL-700gE router), corresponding PCI BAR
is 0 and the following inb() causes a kernel oops.

The intent behind siimage_reset() was probably to hard reset the interface and
the SATA PHY but as the code writes to two reserved bits instead, it obviously
has been ineffective from the start. So, just remove it.

Make sure to not clear the other IDE channel's interrupt when clearing an IDE
interrupt via the MRDMODE register.
Thanks to Bart for finding a coding mistake.
Bart:
This fixes regression from commit 66602c83dc
("cmd64x: use interrupt status from MRDMODE register (take 2)").
Extra thanks to Martin for reporting and bisecting the issue.

In piix.c (and in ata_piix.c) are already included some patches to skip the
cable check on some laptops and to enable UDMA > 33 modes, but I've noticed
than theese doesn't work on my Acer Aspire 5602WLMi (maybe exist more
versions of this laptop). With this simple patch I can set transfer mode
to UDMA100.

It turns out that const and __{dev}initdata cannot be mixed currently
and that generic IDE PCI host driver is also affected by the same issue:

This patch workarounds the problem in a bit hackish way but without
removing const from generic_chipsets[] (it adds const to __setup() so
__setup_str_ide_generic_all becomes const).
Now all __{dev}initdata data in generic IDE PCI host driver are read-only
so it builds again (driver's .init.data section gets marked as READONLY).

This patch workarounds the problem by making static struct hpt_info instances

It turns out that const and __{dev}initdata cannot be mixed currently.
This patch workarounds the problem by removing __devinitdata tag from 'primary'
variable (which makes 'primary' to be moved from .init.data to .bss section).
Now all __devinitdata data in cy82c693 host driver are read-only so it builds
again (driver's .init.data section gets marked as READONLY).
While at it:
* Move 'primary' variable to its only user, init_iops_cy82c693().
* Bump driver version.
