This provides some serious scheduling for the Nomadik family by introducing a sched_clock() using the MTU clock source in the same manner as e.g. OMAP or U300. This type of solutions has been discussed at no end in the past, however we need this resolution for making measurements and using HRTimers.

Set a default trigger type for interrupts, otherwise if request_irq is called without specifiying a trigger type, the interrupt will not actually be enabled.

On this peripheral, setting the trigger type enables the interrupt, and the current set_type() implementation unconditionally enables the interrupt, even if it is called when the interrupt is disabled. Fix set_type() to: - if the interrupt is disabled, defer the actual trigger setting to when it is unmasked - if the interrupt is enabled, change the type immediately by clearing the old type and then re-enabling with the new type.

This is a complete rewrite of the MTU driver, using one-shot for events and a free-running timer for stamping. It allows CONFIG_NO_HZ and CONFIG_HIGH_RES_TIMERS to work on Nomadik and Ux500.

On the U8500 platform there are four GPIO blocks, each with a 4K address space, including the peripheral identification. However, each of these blocks have a varying number of banks, each of which have 32 GPIOs and an interrupt line. The current nomadik-gpio driver implementation can handle each of these sub-banks easily with one instance each, but cannot as-is be hooked up to them because it is an AMBA driver and it expects to see a peripheral with the appropriate peripheral ids but having only one bank and only one interrupt. Solve this by converting the driver to a platform driver.

Since we register as a chained handler, we need to take care of acking the parent irq. Current code had the acking disabled because just acking the interrupt disables it on some interrupt controllers (like the VIC used on Nomadik). However, not acking at all is incorrect because interrupt controllers like the GIC need an EOI indication, which is done in the ack routine. Solve this by maskacking and unmasking it appropriately, similar to how handle_level_irq operates.

Move the Nomadik GPIO driver to plat-nomadik so that it can also be used on the Ux500 platform. The mach-nomadik include/mach/gpio.h is replaced by one that includes the one now in plat-nomadik, so that code doesn't need to include the one in plat specifically, and can instead use <linux/gpio.h> as usual.
