6905a65879 ARM: Make the sched_clock framework mandatory
All sched_clock() providers have been converted to the sched_clock
framework, which also provides a jiffy based implementation for
the platforms that do not provide a counter.

It is now possible to make the sched_clock framework mandatory,
effectively preventing new platforms to add new sched_clock()
functions, which would be detrimental to the single zImage work.

bc8d849d91 ARM: prima2: convert to common sched_clock() implementation
Prima2 has its own sched_clock() implementation, which gets in the
way of a single zImage. Moving to the common sched_clock framework
makes the code slightly cleaner (the mapping hack in sched_clock()
goes away...).

dffcb9c5f8 ARM: 7300/1: realview: fix definition of GPIO0 interrupt on PB1176 to match TRM
Currently, -1 is used as the GPIO0 interrupt on realview PB1176 and an
AMBA device is registered with this parameter. With the pending NO_IRQ
cleanup, this will lead to a warning at boot time, since -1 is obviously
broken.

This patch updates the interrupt used for GPIO0 to match that specified
by the TRM. Unfortunately, it's not clear how to trigger this interrupt
so we trust that the documentation is correct.
