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:
