[][openwrt-24][mt7988][bsp][Fix ETH driver bring up issue when eth2 SFP is enabled]

[Description]
Fix ETH driver bring up issue when eth2 SFP is enabled.

Due to the ETH2 SFP needs to use I2C1, and the pins for I2C1 are
occupied by ETH for adjusting the MDIO driving strength, once I2C1
is initialized, it causes the ETH driver to fail to initialize.
As a result, none of the ETH network interfaces are brought up.

Without this patch, the ETH driver is unable to bring up when eth2
SFP is enabled.

Brief introduction for using MediaTek released OpenWrt SDK

1. Build system setup

2. Clone vanilla OpenWrt

Currently two release branches are supported:

  1. 21.02 This is the current in-use branch

    git clone -b openwrt-21.02 https://git.openwrt.org/openwrt/openwrt.git
    
  2. master (will be 24.0x branch later) The next version in development

    git clone https://git.openwrt.org/openwrt/openwrt.git
    

3. Add MediaTek OpenWrt feed

cd openwrt
echo "src-git mtk_openwrt_feed https://git01.mediatek.com/openwrt/feeds/mtk-openwrt-feeds" >> feeds.conf.default
./scripts/feeds update -a
./scripts/feeds install -a

4. Apply MediaTek OpenWrt files and patches

  1. 21.02 branch

    cp -af ./feeds/mtk_openwrt_feed/21.02/files/* .
    cp -af ./feeds/mtk_openwrt_feed/tools .
    for file in $(find ./feeds/mtk_openwrt_feed/21.02/patches-base -name "*.patch" | sort); do patch -f -p1 -i ${file}; done
    for file in $(find ./feeds/mtk_openwrt_feed/21.02/patches-feeds -name "*.patch" | sort); do patch -f -p1 -i ${file}; done
    
  2. master branch

    cp -af ./feeds/mtk_openwrt_feed/master/files/* .
    for file in $(find ./feeds/mtk_openwrt_feed/master/patches-base -name "*.patch" | sort); do patch -f -p1 -i ${file}; done
    

5. Configuration

make menuconfig
  1. 21.02 branch

    Target System -> MediaTek Ralink ARM
    Subtarget -> MT7981 / MT7986 / MT7988
    Target Profile -> select as needed
    
  2. master branch

    Target System -> MediaTek Ralink ARM
    Subtarget -> Filogic 8x0 (MT798x)
    Target Profile -> select as needed
    

6. Build

make V=s -j$(nproc)
