This pull request contains the DT changes for BCM2835 in 4.4.  It
pulls in clk/clk-bcm2835 (which Stephen Boyd has said would be stable)
because the DT changes to enable the clock driver need the driver
itself to be present. These changes include the following:

- Eric Anholt, moves the bcm2835 clock driver under bcm/ where it belongs with
  other Broadcom clock providers drivers, defines the binding for new clock
  driver, adds support for programming the BCM2835 audio domain, adds the DDC I2C
  controller to Device Tree, and finally migrates the Device Tree to use the new
  clock driver binding

- Lubomir Rintel adds support for the Raspberry Pi Model A+ and B revision 2, and
  remove the I2S controller which is non-existent on Raspberry Pi Model B

- Stefan Wahren adds an uart0 label for referencing the UART adapter

We need to use it for getting video modes over HDMI.

Signed-off-by: Eric Anholt <eric@anholt.net>
Acked-by: Stephen Warren <swarren@wwwdotorg.org>

This will give us the ability to set the pixel and HDMI state machine
clocks for the VC4 KMS driver, change the CPU frequency, and
potentially gate clocks in the future (once we also write a power
domain driver).  It also gives the uart an explicit clock reference,
so that we don't need to change the physical addresses of the old
fixed clk_bcm2835.c clocks for Raspberry Pi 2 port.

Two clocks get their frequencies updated as a result of this.  One is
uart's apb_pclk, which was previously accidentally grabbing the fixed
uart0_pclk due to the apb_pclk not having clk_register_clkdev()
called.  The uart doesn't seem to do anything with apb_pclk other than
make sure it's on, so that appears safe (also, as far as I can see,
the apb clock is actually the same as the VPU clock).  The other is
EMMC, which according to the docs was supposed to be in the 50-100Mhz
range, but it turns out the firmware needed to change to running it at
the 250Mhz core clock speed to avoid a bug in clock domain crossing.

Additionally, anything using BCM2835_CLOCK_VPU will now have a correct
clock rate if the user configures the boot-time core clock speed using
config.txt.
