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.

ARMv8/FSL_LSCH3: Add FSL_LSCH3 SoC Freescale LayerScape with Chassis Generation 3 is a set of SoCs with ARMv8 cores and 3rd generation of Chassis. We use different MMU setup to support memory map and cache attribute for these SoCs. MMU and cache are enabled very early to bootst performance, especially for early development on emulators. After u-boot relocates to DDR, a new MMU table with QBMan cache access is created in DDR. SMMU pagesize is set in SMMU_sACR register. Both DDR3 and DDR4 are supported.

armv8/fsl_lsch3: Change arch to fsl-layerscape There are two LS series processors are built on ARMv8 Layersacpe architecture currently, LS2085A and LS1043A. They are based on ARMv8 core although use different chassis, so create fsl-layerscape to refactor the common code for the LS series processors which also paves the way for adding LS1043A platform.

armv8/fsl-lsch3: Update code to release secondary cores NXP ARMv8 SoC LS2080A release all secondary cores in one-go. But other new SoCs like LS2088A, LS1088A release secondary cores one by one.

armv8/fsl-lsch3: Release secondary cores from boot hold off with Boot Page Secondary cores need to be released from holdoff by boot release registers. With GPP bootrom, they can boot from main memory directly. Individual spin table is used for each core. Spin table and the boot page is reserved in device tree so OS won't overwrite.
