ARM: SoC cleanups for 3.17 

This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.

What: /sys/devices/*/<our-device>/fuse
Date: February 2014
Contact: Peter De Schrijver <pdeschrijver@nvidia.com>
Description: read-only access to the efuses on Tegra20, Tegra30, Tegra114
and Tegra124 SoC's from NVIDIA. The efuses contain write once
data programmed at the factory. The data is layed out in 32bit
words in LSB first format. Each bit represents a single value
as decoded from the fuse registers. Bits order/assignment
exactly matches the HW registers, including any unused bits.
Users: any user space application which wants to read the efuses on
Tegra SoC's

It was decided to remove plat-s5pc1xx as some of the support was already
in plat-s5p or plat-samsung, with the S5PC110 support added with S5PV210
the only user was the S5PC100. The S5PC100 specific items where moved to

NVIDIA Tegra20/Tegra30/Tegr114/Tegra124 fuse block.
Required properties:
- compatible : should be:
"nvidia,tegra20-efuse"
"nvidia,tegra30-efuse"
"nvidia,tegra114-efuse"
"nvidia,tegra124-efuse"
Details:
nvidia,tegra20-efuse: Tegra20 requires using APB DMA to read the fuse data
due to a hardware bug. Tegra20 also lacks certain information which is
available in later generations such as fab code, lot code, wafer id,..
nvidia,tegra30-efuse, nvidia,tegra114-efuse and nvidia,tegra124-efuse:
The differences between these SoCs are the size of the efuse array,
the location of the spare (OEM programmable) bits and the location of
the speedo data.
- reg: Should contain 1 entry: the entry gives the physical address and length
of the fuse registers.
- clocks: Must contain an entry for each entry in clock-names.
See ../clocks/clock-bindings.txt for details.
- clock-names: Must include the following entries:
- fuse
- resets: Must contain an entry for each entry in reset-names.
See ../reset/reset.txt for details.
- reset-names: Must include the following entries:
- fuse
Example:
fuse@7000f800 {
compatible = "nvidia,tegra20-efuse";
reg = <0x7000F800 0x400>,
<0x70000000 0x400>;
clocks = <&tegra_car TEGRA20_CLK_FUSE>;
clock-names = "fuse";
resets = <&tegra_car 39>;
reset-names = "fuse";
