With the addition of automatically ACPI GPIO assignment to i2c
client->irq we can now remove the code the does the ACPI GPIO probing
for drivers that use a single interrupt.
Tested on hardware only on bmc150-accel, rest of the drivers where
compile tested only.

Since commit dab472eb931bc291 ("i2c / ACPI: Use 0 to indicate that
device does not have interrupt assigned") 0 is not a valid i2c
client irq anymore, so change all driver's checks accordingly.
The same issue occurs when the device is instantiated via device tree
with no IRQ, or from the i2c sysfs interface, even before the patch
above.

Commit 845c877009cf014b ("i2c / ACPI: Assign IRQ for devices that have
GpioInt automatically") automatically asigns the first ACPI GPIO
interrupt in client->irq, so we can remove the probing code from
drivers that use only one interrupt.

Fixed up description and applied to the togreg branch of iio.git.
Initially pushed out as testing. Nice to finally clear this lot
out! Now I just have to remember that we don't need this boiler

Applied to the togreg branch of iio.git. Initially pushed out as
testing for the autobuilders to play with it.
