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.

Add the cpu.c and dev.c and modify w90p910 platform
to apply to use the common API(provided by cpu.c and dev.c)
at the same time, I renamed all w90x900 to nuc900 in every
c file of w90x900 platform and touchscreen's driver name.
