driver in drivers/net is contained in a separate patch.

This patch adds OHCI support to the LPC32xx ARM platform. Besides the trivial
addition of platform "usb-ohci" support, fixes for the USB PLL have been added
to arch/arm/mach-lpc32xx/clock.c, ported from NXP's lpclinux.com.

(This is the mach-lpc32xx specific part, the USB subsystem specific changes are
in a separate patch for the USB maintainers.)

Some of the LPC32XX_* macros were typed ("LCP32XX_*"), which is fixed by this
patch. (Besides another LCP doc typo.)

Further, the LPC32XX_GPIO_P2_MUX_SET/CLR/STATE macros were missing.

The GPI_28 IRQ was not registered properly. The registration of
IRQ_LPC32XX_GPI_28 was added and the (wrong) IRQ_LPC32XX_GPI_11 at
LPC32XX_SIC1_IRQ(4) was replaced by IRQ_LPC32XX_GPI_28 (see manual of
LPC32xx / interrupt controller).

Remove the now empty arch_reset() from all the mach/system.h includes,

no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

The sysdev code will be going away soon, so this include needs to be

Boards used to specify zreladdr in their Makefile.boot with
zreladdr-y := x, so conflicting zreladdrs were silently overwritten.
This patch changes this to zreladdr-y += x, so that we end
up with multiple words in zreladdr in such a case. We can
detect this later and complain if necessary.

Some platforms (like OMAP not to name it) are doing rather complicated
hacks just to determine the base UART address to use.  Let's give their
addruart macro some slack by providing an extra work register which will
allow for much needed cleanups.

This is basically a no-op as this commit is only adding the extra argument
to the macro but no one is using it yet.
