ARM: bcm2835: perf_event support for Raspberry-Pi

The following patch enables performance counter support on Raspberry-Pi.

We have this working on the 2708 based rasp-pi kernels by manually putting
the device registration in the platform files.

This change does things properly in a device tree.  The boot messages look
proper, but my rasp-pi hangs somewhere in USB enabling when running a
stock 3.13-rc6 kernel so I have been unable to fully test this change.

I also understand that the rasp-pi 1176 pmu support is missing the
overflow interrupt.  I'm not sure if that's true of all 2835
implementations.  If not, then this patch will need to be changed a bit.

ARM: 7902/1: sa1100: h3xxx: move serial port GPIO handling to common place

Both h3100 and h3600 request UART gpios during init_machine time. As
sa1100 gpio driver is going to become proper machine driver, move gpio
handling to UART port functions. Request all gpios using gpio_request
array once and then guard them from rerequesting with bool variable.
