ARM: lpc32xx: clean up header files

All device drivers have stopped relying on mach/*.h headers,
so move the remaining headers into arch/arm/mach-lpc32xx/lpc32xx.h
to prepare for multiplatform builds.

The mach/entry-macro.S file has been unused for a long time now
and can simply get removed.

ARM: lpc32xx: Use kmemdup to replace duplicating its implementation

kmemdup is better than kmalloc() + memcpy(), and we do not like
open code. So just use kmemdup instead.

ARM: lpc32xx: remove unused header file clock.h

The removed clock.h file is a leftover after moving the platform to a
common clock framework driver, it contains unused "struct clk"
definition, which under circumstances may coalesce with a generic
"struct clk" declaration for clock consumers. Also remove useless
include of the removed local file from a single source file
mach-lpc32xx/pm.c.

suspend: constify platform_suspend_ops

While at it, fix two checkpatch errors.
Several non-const struct instances constified by this patch were added after
the introduction of platform_suspend_ops in checkpatch.pl's list of "should
be const" structs (79404849e90a41ea2109bd0e2f7c7164b0c4ce73).

Patch against mainline.
Inspired by hunks of the grsecurity patch, updated for newer kernels.
