hwrng: ixp4xx - Make use of the helper function devm_platform_ioremap_resource()

Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately

hw_random: ixp4xx: Add OF support

This makes the hardware random number generator found in
the IXP46x SoCs probe from the device tree.

hw_random: ixp4xx: Turn into a module

Instead of just initializing always, which will invariably
create problems on multiplatform builds, turn this driver into
a module and pass a resource with the memory location.
The device only exist on the IXP46x so we only register
the device for the IXP46x SoC.

hw_random: ixp4xx: enable compile-testing

The driver is almost portable already, it just needs to
include the new header for the cpu definition.

[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach

This just leaves include/asm-arm/plat-* to deal with.

[ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

[PATCH] Fix HWRNG built-in initcalls priority

This changes all HWRNG driver initcalls to module_init(). We must probe
the RNGs after the major kernel subsystems are already up and running (like
PCI).

This fixes Bug 7730.
