[][kernel][mt7988][eth][Update 36-bit DMA feature to resolve panic issue]

[Description]
Refactor 36-bit DMA feature to resolve panic issue.

In the previous change with ID @9236901, we refactor the 36-bit DMA
feature to an upstream style, inadvertently introducing a potential
risk of losing the upper 4 bits of the DMA addressin the mtk_poll_rx()
function during SER.

Without this patch, the kernel will panic in the mtk_rx_clean() function
during SER test.

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
