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>

arm: socfpga: Restructure clock manager driver Restructure clock manager driver in the preparation to support A10. Move the Gen5 specific code to _gen5 files. - Change all uint32_t to u32 and change to use macro BIT(n) for bit shift. - Check return value from wait_for_bit(). So change return type to int for cm_write_with_phase() and cm_basic_init(). Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com>

arm: socfpga: clock: Add code to read clock configuration Add the entire bulk of code to read out clock configuration from the SoCFPGA CPU registers. This is important for MMC, QSPI and UART drivers as otherwise they cannot determine the frequency of their upstream clock.
