kernel: x86_64: drop CALGARY IOMMU

The calgary IOMMU was only used on high-end IBM systems in the early
x86_64 age.  This is an unlikely OpenWrt target and in fact upstream
are looking to drop the driver entirely with the bonus that we no
longer see:

[ 0.000000] Calgary: detecting Calgary via BIOS EBDA area
[ 0.000000] Calgary: Unable to locate Rio Grande table in EBDA - bailing!
