SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

imx: mx7ulp: Add clock framework and functions Add a clock framework to support SCG1/PCC2/PCC3 for A7 to support get/set clock source, divider, clock rate and parent source. Users need to include pcc.h to use the APIs to for peripherals clock. Each peripheral clock is defined in enum pcc_clk type. SCG relevants APIs are defined in scg.h which supports clock rate get, PLL/PFD enablement and settings, and all SCG clock initialization. User need use enum scg_clk to access each clock source. In clock.c, we initialize necessary clocks at u-boot s_init and implement the clock functions used by driver modules to operate clocks dynamically.
