[PATCH] ACPI: resource: Do IRQ override on MECHREV GM7RG7M

[Andrei Galiant]

The MECHREV Jiaolong17 Series GM7RG7M (TongFang GM7RG7M, Ryzen 7
6800H) describes the PS/2 keyboard interrupt in its DSDT as
edge-triggered, active-low and shared:

    IRQ (Edge, ActiveLow, Shared) {1}

The keyboard controller actually asserts IRQ 1 active-high.  On AMD
Zen systems acpi_dev_irq_override() skips the ACPI IRQ override for
GSI 1, so the IO-APIC redirection entry is programmed with the DSDT's
active-low polarity and the interrupt is never delivered: the embedded
controller still scans the matrix and places scancodes in port 0x60,
but atkbd_receive_byte() is never called and the internal keyboard is
dead under Linux, while it works in the firmware setup, in GRUB and in
Windows.

Add the board to irq1_edge_low_force_override[] so that the standard
edge/high override is applied, matching the already-listed sibling
GM7XG0M (Jiaolong17KS).
