powerpc/dts: Add and fix 1588 timer node for eTSEC
Add 1588 timer node in files:
arch/powerpc/boot/dts/bsc9131rdb.dtsi
arch/powerpc/boot/dts/bsc9132qds.dtsi
arch/powerpc/boot/dts/p1010rdb.dtsi
arch/powerpc/boot/dts/p1020rdb-pd.dts
arch/powerpc/boot/dts/p1021rdb-pc.dtsi
arch/powerpc/boot/dts/p1022ds.dtsi
arch/powerpc/boot/dts/p1025twr.dtsi
For P2020RDB-PC, registers' values should be calculated
based on default 1588 reference clock(300MHz) not 250MHz,
and fix this in file:
arch/powerpc/boot/dts/p2020rdb-pc.dtsi
