Clean up the types of a few strings to make them const when they are never
written to.

MFC r273914:

The command name is a constant, use the correct type.
MFC 273927:

Move the definitions of the fdt functions from a uboot header to a new fdt
header. There is nothing in the fdt spec that ties it to U-Boot.

While here sort and fix the signature of fdt_setup_fdtp.

MFC 273934:

Start to allow platforms other than U-Boot to use the FDT code in loader by
moving U-Boot specific code from libfdt.a to a new libuboot_fdt.a. This
needs to be a new library for linking to work correctly.

Some device tree configurations place the generic timer under the root
of the tree and not under simplebus. Update the driver to handle this.

Clean up our ARM assembly:

MFC 275256:

Switch to the ARM unified assembly language as the clang integrated as only
supports it. Binutils supports it when the ".syntax unified" directive
is set.

MFC 275264:

Update _ENTRY to use _EENTRY to reduce the common code.

MFC 275321:

Remove extra labels, ENTRY_NP already provides them.

Correctly a few incorrect uses of ENTRY/EENTRY and END/EEND

Set the alignment to 4-bytes after a string as clang 3.5 can switch to
thumb mode if this is incorrect.

MFC 275522:

Place the literal pool after a RET otherwise clang 3.5 tries to put it too
far away from a ldr psuedo instruction. With this clang will place the
literal value here where it's close enough to be loaded.

MFC 275524:

Switch to a .cpu directive. These will work when clang 3.5 is imported
where the .arch directive is a nop.

MFC r268576: sh: Correctly handle positional parameters beyond INT_MAX on
64-bit systems.

Currently, there can be no more than INT_MAX positional parameters. Make
sure to treat all higher ones as unset to avoid incorrect results and
crashes.

On 64-bit systems, our atoi() takes the low 32 bits of the strtol() and
sign-extends them.

On 32-bit systems, the call to atoi() returned INT_MAX for too high values
and there is not enough address space for so many positional parameters, so
there was no issue.
