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. Signed-off-by: Phil Edworthy <phil.edworthy@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
