(only 1 write operation).

This patch adds support for :
- Rate calculation through muxes and generic dividers
- Basic gate setting propagation
- Reparenting for muxes
- Clock rate setting through generic dividers without reparenting

Support is only added to the Composite VPU and VAPB clocks in order
to support the Video Processing Unit Power Domain clock setup.

The Amlogic Meson SoCs embeds a specific Power Domain dedicated to the
Video Processing Unit.
This patch implements support for this power domain in preparation of the
future support for the Video display support in U-Boot.

This driver will depend on changes in the clock driver to handle the setup
of the VPU and VAPB clocks configured from DT using assigned-clocks entries.

In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's <inttypes.h>.
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

[trini: Reword the commit message to be clear this is a direct problem
rather than just a warning]

The existing imx_watchdog driver is compatible with mx25 chipsets.
Add a WDOG1_BASE_ADDR define for the base address and enable the driver
in watchdog's Makefile.

To use the driver, a board must define CONFIG_IMX_WATCHDOG and
CONFIG_HW_WATCHDOG.

This fixes an issue when booting an mx25 chip via usb/serial. In this
case, the boot rom will always enable the watchdog. If u-boot is running
in interactive mode and the watchdog is not serviced, the system is
rebooted when the watchdog expires.

With upcoming changes that require CONFIG_BLK, this broke
USB Mass Storage on the OMAP3 boards because if CONFIG_BLK is
enabled, it assumes that DM_USB is enabled, but it wasn't yet
available on omap3 and omap4 boards.

This patch converts the OMAP2430 MUSB glue to support DM_USB and
extracts the necessary information based on the device tree.

It's based on the ti-musb driver, but there are enough significant
differences in both the architecture and device tree entires between
am33xx and OMAP3/OMAP4, that I think it makes sense to continue to
keep the separate.

Per doc/driver-model/usb-info.txt, the USB gadget stuff hasn't
migrated to DM_USB yet, so this only supports USB Host for now.

Users wanting USB Gadgets will need to disable DM_USB and leave
it the old way for now.

At present if TSC frequency is provided in the device tree, it takes
precedence over hardware calibration result. This swaps the order to
