[ Upstream commit a9c4a912b7dc7ff922d4b9261160c001558f9755 ]
commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen platforms") attempted to overhaul the override logic so it didn't apply on X86 AMD Zen systems. This was intentional so that systems would prefer DSDT values instead of default MADT value for IRQ 1 on Ryzen 6000 systems which typically uses ActiveLow for IRQ1.
This turned out to be a bad assumption because several vendors add Interrupt Source Override but don't fix the DSDT. A pile of quirks was collecting that proved this wasn't sustaintable.
Furthermore some vendors have used ActiveHigh for IRQ1. To solve this problem revert the following commits: * commit 17bb7046e7ce ("ACPI: resource: Do IRQ override on all TongFang GMxRGxx") * commit f3cb9b740869 ("ACPI: resource: do IRQ override on Lenovo 14ALC7") * commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad") * commit 7592b79ba4a9 ("ACPI: resource: do IRQ override on XMG Core 15") * commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen platforms")
