Before this commit the code for determining the disconnect threshold was checking for sun4i or sun6i assuming that those where the exception and that newer SoCs use a disconnect threshold of 2 like sun7i does.
But it turns out that newer SoCs actually use a disconnect threshold of 3 and sun5i and sun7i are the exceptions, so check for those instead.
Here are the settings from the various Allwinner SDK sources: sun4i-a10: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun5i-a13: USBC_Phy_Write(usbc_no, 0x2a, 2, 2); sun6i-a31: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun7i-a20: USBC_Phy_Write(usbc_no, 0x2a, 2, 2); sun8i-a23: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun8i-h3: USBC_Phy_Write(usbc_no, 0x2a, 3, 2); sun9i-a80: USBC_Phy_Write(usbc_no, 0x2a, 3, 2);
Note this commit makes no functional changes for sun4i - sun7i, and changes the disconnect threshold for sun8i to match what Allwinner uses.
