iommu/amd: Fix ill-formed ivrs_ioapic, ivrs_hpet and ivrs_acpihid options
[ Upstream commit 1198d2316dc4265a97d0e8445a22c7a6d17580a4 ]
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: ca3bf5d47cec ("iommu/amd: Introduces ivrs_acpihid kernel parameter")
