Kim Phillips 7e8834776c iommu/amd: Fix ill-formed ivrs_ioapic, ivrs_hpet and ivrs_acpihid options 
commit 1198d2316dc4265a97d0e8445a22c7a6d17580a4 upstream.

Currently, these options cause the following libkmod error:

libkmod: ERROR ../libkmod/libkmod-config.c:489 kcmdline_parse_result: \
	Ignoring bad option on kernel command line while parsing module \
	name: 'ivrs_xxxx[XX:XX'

Fix by introducing a new parameter format for these options and
throw a warning for the deprecated format.

Users are still allowed to omit the PCI Segment if zero.

Adding a Link: to the reason why we're modding the syntax parsing
in the driver and not in libkmod.

Fixes: ca3bf5d47c ("iommu/amd: Introduces ivrs_acpihid kernel parameter")
