It contains a bunch of imx soc updates for 3.12.

- Add more ethernet phy fixups for imx6 boards
- Add some missing imx6q clocks into clock driver
- Add new clock types fixup mux and div to work around some ugly
  hardware defect
- Consolidate L2 cache initialization function, so that it can be used
  on more i.MX SoCs
- Replace magic numbers in mach-imx6q.c with well defined macros
- Small fixes for imx6q and pllv3 clock drivers
- Some random updates on imx defconfig files

Add defines for common Micrel PHY setups so that other platforms
can use them. Update imx61 and sama5 hardware to use the micrel_phy.h
PHY defines.

Also add support for the KSZ9021RLRN PHY.

Commit 02502da4 (ASoC: imx-mc13783: Depend on ARCH_ARM) caused the selection of
CONFIG_SND_SOC_IMX_MC13783 to be impossible due to a wrong dependency, which
caused CONFIG_SND_SOC_IMX_MC13783 to be removed after the defconfigs cleanups.

The original selection problem has been fixed by 9f19de64 (ASoC: imx-mc13783:
Make SND_SOC_IMX_MC13783 visible again), so it is possible to select
CONFIG_SND_SOC_IMX_MC13783 again as originally done.

There are two improvements for this commit:

- Add comparing pll lock condition after while loop. It can
fix potential fake timeout problem caused by the code is just
scheduled out before compare the timeout, and the time of
scheduling out are more than one jiffies.

- Move timeout assignment more close to compare the timeout.
It can reduce the possibility the code is scheduled out, and
the timeout can be more precise.

All the clocks controlled by the register 'CCM Serial Clock
Multiplexer Register 1' should be fixup clocks. This patch

One register may have several fields to control some clocks. It
is possible that the read/write values of some fields may map to
different real functional values, so writing to the other fields
in the same register may break a working clock tree. A real case
is the aclk_podf field in the register 'CCM Serial Clock Multiplexer
Register 1' of i.MX6Q/SDL SoC. This patch introduces a fixup hook
for multiplexer clock which is called before writing a value to
clock registers to support this kind of multiplexer clocks.
