ipq/arm: Redesign hooks for bootblock
The following patches had to be squashed to properly build all the different ARM boards. ipq8064: storm: re-arrange bootblock initialization The recent addition of the storm bootblock initialization broke compilation of Exynos platforms. The SOC specific code needs to be kept in the respective source files, not in the common CPU code. As of now coreboot does not provide a separate SOC initialization API. In general it makes sense to invoke SOC initialization from the board initialization code, as the board knows what SOC it is running on. Presently all what's need initialization on 8064 is the timer. This patch adds the SOC initialization framework for 8064 and moves there the related code. BUG=chrome-os-partner:27784 TEST=manual . nyan_big, peach_pit, and storm targets build fine now.

Experience has shown that nearly every board needs either one or both of these hooks, so having explicit Kconfigs for them has become unwieldy. Instead, this patch implements them as a weak symbol that can be overridden by mainboard/SoC code, as the more recent arm64_soc_init() is also doing. Since the whole concept of a single "CPU" on ARM systems has kinda died out, rename bootblock_cpu_init() to bootblock_soc_init(). (This had already been done on Storm/ipq806x, which is now adjusted to directly use the generic hook.) Also add a proper license header to bootblock_common.h that was somehow missing. Leaving non-ARM32 architectures out for now, since they are still using the really old and weird x86 model of directly including a file. These architectures should also eventually be aligned with the cleaner ARM32 model as they mature. BRANCH=None BUG=chrome-os-partner:32123 TEST=Booted on Pinky. Compiled for Storm and confirmed in the disassembly that bootblock_soc_init() is still compiled in and called right before the (now no-op) bootblock_mainboard_init().
