i2c-i801: Remove force_addr parameter
Remove the force_addr module parameter. It doesn't appear to ever
have been needed, and PCI resources shouldn't be arbitrarily
changed anyway.

Add support for the new nForce4 MCP51 (also known as nForce 410 or
430) and nForce4 MCP55 to the i2c-nforce2 driver. Some code changes
were required because the base I/O address registers have changed in
these versions. Standard BARs are now being used, while the original
nForce2 chips used non-standard ones.

Properly document on which systems the i2c-piix4 SMBus driver will
refuse to load. Hopefully this will make it clearer for users, which
were often wondering why their destop or server systems were detected
as laptops.

This patch removes the fix_hstcfg option from the driver and related
SMBus Interrupt Select register magic because now we know what are
valid values for this register. This patch updates the documentation
and adds new IRQ mode check so we are sure not to miss any new
"unusual" value.
The PCI quirk for users of fix_hstcfg was not developed because the
chipset lacks of subsystem ID registers and DMI is stated "To be
filled". Impact to existing systems is minimal because the problem
showed up on motherboards like 10 years back. On the other hand users
of newer Serverworks and HT1000 systems won't be misleaded by the
message suggesting to try the fix_hstcfg any more.

This patch forces the user to specify what type of adapter is present when
loading i2c-parport or i2c-parport-light. If none is specified, the driver
init simply fails - instead of assuming adapter type 0.
This alleviates the sometimes lengthy boot time delays which can be caused
by accidentally building one of these into a kernel along with several i2c
slave drivers that have lengthy probe routines (e.g. hwmon drivers).
Kconfig and documentation updated accordingly.

Add Broadcom HT-1000 south bridge's PCI ID to i2c-piix driver. Note
that at least on Supermicro H8SSL it uses non-standard SMBHSTCFG = 3
and standard values like 0 or 9 causes hangup.

Do not limit the usage count of i2c clients to 1. In other words,
change the client usage count behavior from the old I2C_CLIENT_ALLOW_USE
to the old I2C_CLIENT_ALLOW_MULTIPLE_USE. The rationale is that no
driver actually needs the limiting behavior, and the unlimiting
behavior is slightly easier to implement.
Update the documentation to reflect this change.

Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
can simply make it the default and drop the flag. If any driver really
doesn't want to be notified when i2c adapters are added, that driver
can simply omit to set .attach_adapter. This approach is also more
robust as it prevents accidental NULL pointer dereferences.

The big i2c-viapro SMBus driver update which went into 2.6.14-git1
introduced a few minor issues. Nothing critical, but I would like a
few adjustments to be merged in to fix the following problems:
* VIA should not be spelled Via.
* Frodo Looijaard and Philip Edelbrock did not write the i2c-viapro
driver.
* When debugging is disabled, half of messages would be logged.
* Drop an unneeded masking.
* Some port reads can be avoided now that the transaction size is
passed as a parameter to vt596_transaction().
* SMBus Receive Byte transactions are used for probing too (for
EEPROMs), so hide errors on these too.
