All device DTS files in the target set the serial0 property to the
same value (*). So, let's move the definitions to the DTSI files.
That's also where the kernel defines it (qcom-ipq8064-v1.0.dtsi).
* The only exception is ipq8064-db149, which defines
"serial0 = &uart2;", but inside a block called "alias" instead of
"aliases". It must be assumed that this is broken anyway, so we
don't touch it here.
