rk3288: Change all SoC headers to <soc/headername.h> system
This patch is the start of a series to change all non-x86 SoC-specific headers to be included as <soc/header.h> instead of the old <soc/vendor/chip/header.h> or "header.h". It will add an include/soc/ directory under every src/soc/vendor/chip/ and append the .../include/ part of that to the global include path. This matches the usage of <arch/header.h> for architecture-specific headers and had already been done for some headers on Tegra. It has the advantage that a source file which does not know the specific SoC used (e.g. Tegra files common for multiple chips, or a global include file) can still include SoC-specific headers and access macros/types defined there. It also makes the includes for mainboard files more readable, and reduces the chance to pull in a wrong header when copying mainboard sources to use a different-related SoC (e.g. using a Tegra124 mainboard as template for a Tegra132 one). For easier maintainability, every SoC family is modified individually. This patch starts out by changing Rk3288. Also alphabetized headers in affected files since we touch them anyway. BUG=None TEST=Whole series: compared binary images for Daisy, Nyan_Blaze, Rush_Ryu, Storm, Urara and Veyron_Pinky. Confirmed that they are byte-for-byte identical except for timestamps, hashes, and __LINE__ macro replacements. Compile-tested individual patches.
