Phil Edworthy 99744b7e34 sh: Add SH7269 device and RSK2+SH7269 board
This is an sh2a device (max 266MHz) with FPU, video display
controller (VDC), 8 serial ports, 4 I2C channels, 3 CAN ports,
SD and on-chip USB.

The RSK2+SH7269 board uses the SH7269 processor. It is often
referred to as just rsk7269.
