bcm2835: add sdhost and gpio controllers
...
This adds the bcm2835_sdhost and bcm2835_gpio to the BCM2835 platform.
For supporting the SD controller selection (alternate function of GPIOs
48-53), the bcm2835_gpio now exposes an sdbus.
It also has a link to both the sdbus of sdhci and sdhost controllers,
and the card is reparented from one bus to another when the alternate
function of GPIOs 48-53 is modified.

target-arm: Implement BCM2835 hardware RNG
...
Recent vanilla Raspberry Pi kernels started to make use of
the hardware random number generator in BCM2835 SoC. As a
result, those kernels wouldn't work anymore under QEMU
but rather just freeze during the boot process.
This patch implements a trivial BCM2835 compatible RNG,
and adds it as a peripheral to BCM2835 platform, which
allows to boot a vanilla Raspberry Pi kernel under Qemu.
Changes since v1:
* Prevented guest from writing [31..20] bits in rng_status
* Removed redundant minimum_version_id_old
* Added field entries for the state
* Changed realize function to reset

bcm2835_dma: add emulation of Raspberry Pi DMA controller
...
At present, all DMA transfers complete inline (so a looping descriptor
queue will lock up the device). We also do not model pause/abort,
arbitrarion/priority, or debug features.

bcm2835_fb: add framebuffer device for Raspberry Pi
...
The framebuffer occupies the upper portion of memory (64MiB by
default), but it can only be controlled/configured via a system
mailbox or property channel (to be added by a subsequent patch).

* Scratch register
