ARM: kirkwood: add support for OpenBlocks A7 platform
The OpenBlocks A7 board is designed and sold by PlatHome, and based on a Kirkwood 6283 Marvell SoC. It is quite similar to the OpenBlocks A6 already supported in the kernel, with the following main differences: - The A6 uses a RTC on I2C, while the A7 uses the internal SoC RTC. - The A6 has one Ethernet port, while the A7 has two Ethernet ports - The A6 has only one USB port, while the A7 integrates a USB hub, which provides two front-side USB port, and an internal USB port as well. - The A6 has 512 MB of RAM, while the A7 has 1 GB of RAM. - Slightly different GPIOs for some functions.
