20332a066a mx6: soc: update get_cpu_rev and get_imx_type for mx6solo/sololite
Previously, the same value was returned for both mx6dl and mx6solo.
Check number of processors to differeniate.
Also, a freescale patch says that sololite has its cpu/rev
stored at 0x280 instead of 0x260.
I don't have a sololite to verify.

e7bed5c2b3 imx: Use MXC_I2C_CLK in imx i2c driver
i2c didn't work on imx25 due to missing MXC_IPG_PERCLK. Now using
MXC_I2C_CLK on all imx systems using i2c.

0bb7e316f0 i.MX6: provide functional names for CCM_CCGR0-CCGR6 bit fields
Add meaningful constants for each clock channels and use them for
enabling and disabling i.MX6 clocks.

Includes an update to enable/disable the IPU1 clock in
drivers/video/ipu_common to remove IMX5x register access
when used on i.MX6 as discussed in V1:

124a06d7fb imx-common/cmd_bmode.c: add imx bmode (bootmode) command
This is useful for forcing the ROM's
usb downloader to activate upon a watchdog reset.
Or, you can boot from either SD Card.

Currently, support added for MX53 and MX6Q

cac833a98c i.MX6: Add ANATOP regulator init
Init the core regulator voltage to 1.2V. This is required for the correct
functioning of the GPU and when the ARM LDO is set to 1.225V. This is a
workaround to fix some memory clock jitter.

Note: This should be but can't be done in the DCD. The bootloader
      prevents access to the ANATOP registers.
