ARM: driver updates for 3.14

Updates of SoC-near drivers and other driver updates that makes more sense to
 take through our tree.
 
 The largest part of this is a conversion of device registration for some
 renesas shmobile/sh devices over to use resources. This has required
 coordination with the corresponding arch/sh changes, and we've agreed
 to merge the arch/sh changes through our tree.
 
 Added in this branch is support for Trusted Foundations secure firmware,
 which is what is used on many of the commercial Nvidia Tegra products
 that are in the market, including the Nvidia Shield. The code is local
 to arch/arm at this time since it's uncertain whether it will be shared
 with arm64 longer-term, if needed we will refactor later.
 
 A couple of new RTC drivers used on ARM boards, merged through our tree
 on request by the RTC maintainer.
 
 ... plus a bunch of smaller updates across the board, gpio conversions
 for davinci, etc.

Trusted Foundations
-------------------
Boards that use the Trusted Foundations secure monitor can signal its
presence by declaring a node compatible with "tlm,trusted-foundations"
under the /firmware/ node
Required properties:
- compatible: "tlm,trusted-foundations"
- tlm,version-major: major version number of Trusted Foundations firmware

tlm,version-major = <2>;
tlm,version-minor = <8>;
};
};

Some devices (including most Tegra-based consumer devices on the
market) are booted with the Trusted Foundations secure monitor
active, requiring some core operations to be performed by the secure
monitor instead of the kernel.
This option allows the kernel to invoke the secure monitor whenever
required on devices using Trusted Foundations. See
arch/arm/include/asm/trusted_foundations.h or the
tl,trusted-foundations device tree binding documentation for details
on how to use it.
Say n if you don't know what this is about.
