    apm821xx: fixes WNDAP620 + WNDAP660 sysupgrade failures
    
    OpenWRT on the WNDAP6x0 refuses to sysupgrade to itself
    due to a compat_version imbalance. The Image is generated
    with version 2.0, but the uci-defaults says that it needs
    to be at 3.0 for the device.
    
    Fix this by downgrading WNDAP6x0 05_fix-compat-version's
    values back to 2.0 so it matches what we use.
    
    Fixes: 5815884c3a2a ("apm821xx: migrate to DSA")

    (cherry picked from commit e9415be4ad3cacbbd6e65fee5213baf3eaf9e07a)
