i2c-pca-isa: Don't grab arbitrary resources
Grabbing ISA bus resources without anything or anyone telling us we
should can break boot on randconfig/allyesconfig builds by keeping
resources that are in fact owned by different hardware busy and does
as reported by Ingo Molnar.
Generally it's also dangerous to just poke at random I/O ports and
especially those in the range where other old easily confused ISA
hardware might live.
For this specialized I2C bus driver, insist that the user specifies
the resources before grabbing them.
The^WA user of this driver is a one time
echo "options i2c-pca-isa base=0x330 irq=10" >> /etc/modprobe.conf
away from the old behaviour.
