The original clock code from Linux registers some gates at
base + 0x44e0, 0x44f0, 0x4500, 0x4510. These are not in the reference
manual and do not seem to have any effect on the hardware. The
reference manual lists clocks at 0x4700 and 0x4710 which Linux
does not control at all. These clocks really do have an effect on
the hardware and are needed for ethernet support. Register the
existing clocks rather than the made up clocks to support
ethernet.

Add IMX_PLLV3_SYS_VF610 subtype to pllv3 code to be able to control and
re-clock PLL1 and PLL2 on Vybrid SoC. This commit also introduces
imx_clk_pllv3_locked which allows the user to create PLLv3 and specify
how it should be polled for "locked" status (used in .set_rate callback)

Move clk code from 'mach-imx' to 'drivers' to keep the code tree
structure closer to that of analogous one from Linux kernel and,
arguably although subjective, to keep 'mach-imx' less cluttered.
