Fix i2c_board_info definitions - we were defining the 'type' field
of these structures twice since the first argument of I2C_BOARD_INFO
sets this field. Move the second definition into I2C_BOARD_INFO().

Add power management support to the VIC by registering
each VIC as a system device to get suspend/resume
events going.
Since the VIC registeration is done early, we need to
record the VICs in a static array which is used to add
the system devices later once the initcalls are run. This
means there is now a configuration value for the number
of VICs in the system.

period
This provides a 63 bit clock counter guaranteed to be monotonic over a
period of 35583 days instead of a clock wrap every 179 seconds, as long
as sched_clock() is called at least once every 89 seconds. This should
not be a problem in practice, although a kernel timer could be scheduled
every 80 seconds for example simply to call sched_clock() making sure
top bits are always synchronized if need be.

ARM genirq cleanups/updates:
- Start switching platforms to newer APIs
* use "irq_chip" name, not "irqchip"
* providing irq_chip.name
- Show irq_chip.name in /proc/interrupts, like on x86.
This update a bit more than half of the ARM code. The irq_chip.name
values were chosen to match docs (if I have them) or be otherwise
obvious ("FPGA", "CPLD", or matching the code).

If a configuration was chosen to support both the Versatile
AB and PB boards, the result would write to registers not
available on the PB version of the board. Resolve this by
using machine_is_xxx().
Also, for the CLCD, despite how the code looks, both the AB
and PB access the same location to control the clock rate -
it's just called something different between the two board
versions. Invent our own name for this location and use it
unconditionally.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
