ARM: SoC platform updates for v4.10 

These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - Added support for the TI DRA71x family of SoCs in mach-omap2,
   this is an new variant of the the DRA72x/DRA74x automotive
   infotainment chips we already supported for a while.
 
 - Added support for the ST STM32F746 SoC, the first Cortex-M7
   based microcontroller we support, related to the smaller
   STM32F4 family.
 
 - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile,
   see http://elinux.org/RZ-G
 
 - SMP is now supported on the OX820 platform
 
 - A lot of code in mach-omap2 gets removed as a follow-up to
   removing support for board files in the previous release
 
 - Davinci has some new work to improve USB support
 
 - For i.MX, the performance monitor now supports profiling the
   memory controller using 'perf'
 
 Conflicts:
 arch/arm/mach-shmobile/setup-rcar-gen2.c: rcar_gen2_clocks_init()
 is gone, calling of_clk_init(NULL) is sufficient now.

* OMAP3 CONTROL_PADCONF* register offsets for pin-muxing
*
* Extracted from the TRM. Add 0x48002030 to these values to get the
* absolute addresses. The name in the macro is the mode-0 name of
* the pin. NOTE: These registers are 16-bits wide.
*
* Note that 34XX TRM uses MMC instead of SDMMC and SAD2D instead
* of CHASSIS for some registers. For the defines, we follow the
* 36XX naming, and use SDMMC and CHASSIS.
