ARM: imx: clk-vf610: define PLL's clock tree
So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized by boot loader and the kernel code defined fixed rates according to those default configurations. Beginning with the USB PLL7 the code started to initialize the PLL's itself (using imx_clk_pllv3). However, since commit dc4805c2 (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver) imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits, hence the USB PLL were not configured correctly anymore. This patch not only fixes those USB PLL's, but also makes use of the imx_clk_pllv3 for all PLL's and alignes the code with the PLL support of the i.MX6 series.
