This patch removes the use of the IRQF_DISABLED flag
from arch/arm/mach-lpc32xx/timer.c

It's a NOOP since 2.6.35 and it will be removed one day.

The clockevent core is able to figure out the best mult and shift,
calculate min_delta_ns and max_delta_ns, with the necessary info passed
into clockevents_config_and_register().  Use this combined configure
and register function where possible to make the codes less error prone
and gain some positive diff stat.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

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.

In d7e81c26 (clocksource: Add clocksource_register_hz/khz interface) new
interfaces were added which simplify (and optimize) the selection of the
divisor shift/mult constants.  Switch over to using this new interface.
