i2c: add aspeed i2c controller
The Aspeed AST2400 integrates a set of 14 I2C/SMBus bus controllers
directly connected to the APB bus. They can be programmed as master or
slave but the propopsed model only supports the master mode.
On the TODO list, we also have :
- improve and harden the state machine.
- bus recovery support (used by the Linux driver).
- transfer mode state machine bits. this is not strictly necessary as
it is mostly used for debug. The bus busy bit is deducted from the
I2C core engine of qemu.
- support of the pool buffer: 2048 bytes of internal SRAM (not used
by the Linux driver).
