commit b3e76bdc0b2190e67427d31cd740debd01c03631 upstream.

After commit f53947456f98 ("ARM: clk: imx: update pllv3 to support imx7"),
the former used BM_PLL_POWER bit is not correct anymore for IMX7 ENET.
Instead, pll->powerdown holds the correct bit, so using powerdown bit
in clk_pllv3_{prepare | unprepare} functions.
