[PATCH 7/9] ARM: sunxi: dt: Add PLL2 support

Would it be better to name this "allwinner,sun4i-a10-pll2-clk" instead
of "allwinner,sun4i-a10-b-pll2-clk"? By encoding the b in it everyone
is going to wonder what to do on the 'c' revision which is the most
common revision.

The revision based rename would then be from
"allwinner,sun4i-a10-pll2-clk" to "allwinner,sun4i-a10-a-pll2-clk".
