[PATCH] ACPI: resource: Add MECHREVO GM5BG0E to irq1_edge_low_force_override[]

The MECHREVO Jiaolong 15K (GM5BG0E), an AMD Ryzen 7 7435H based laptop,
has a defective DSDT that declares the PS2K keyboard IRQ1 as ActiveLow,
whereas the hardware is actually ActiveHigh. Starting with Linux 6.0,
the kernel no longer auto-corrects this polarity mismatch on AMD Zen
platforms, causing the internal keyboard to become non-functional.

Add the GM5BG0E board to the irq1_edge_low_force_override[] DMI quirk
table so that the kernel forces the correct IRQ polarity for this model.

# 中文版补丁说明

## 问题描述

MECHREVO 蛟龙15K (GM5BG0E) 搭载 AMD Ryzen 7 7435H 处理器，其 BIOS DSDT 表中存在错误：
键盘 IRQ1 被声明为 ActiveLow（低电平触发），但硬件实际为 ActiveHigh（高电平触发）。

从 Linux 6.0 内核开始，AMD Zen 平台不再自动修正此极性不匹配问题，导致内置键盘无法使用。

## 修复方案

将 GM5BG0E 主板添加到内核 `irq1_edge_low_force_override[]` DMI 兼容表中，
使内核为该型号强制使用正确的 IRQ 极性。

# English Version - Patch Description

## Problem Description

The MECHREVO Jiaolong 15K (GM5BG0E), equipped with AMD Ryzen 7 7435H processor,
contains a defective BIOS DSDT table. The PS2K keyboard interrupt (IRQ1) is
declared as ActiveLow in the ACPI table, but the hardware is actually wired
for ActiveHigh operation.

Starting with Linux 6.0, the kernel no longer automatically corrects this
polarity mismatch on AMD Zen platforms (commit 2d331a6ac481), causing the
internal keyboard to become non-functional.

## Solution

Add the GM5BG0E board name to the irq1_edge_low_force_override[] DMI quirk
table in drivers/acpi/resource.c. This forces the kernel to apply the correct
IRQ polarity override for this specific hardware model.

## Technical Details

- **File modified**: drivers/acpi/resource.c
- **Function affected**: acpi_dev_irq_override()
- **Quirk table**: irq1_edge_low_force_override[]
- **DMI match**: DMI_BOARD_NAME = "GM5BG0E"

## Testing

Verified on MECHREVO Jiaolong 15K with:
- AMD Ryzen 7 7435H
- BIOS N.1.23MRO20
- Linux kernel 6.x

After applying this patch, the internal keyboard functions correctly.
