sh: intc - add support for SH7706, SH7707, SH7708, SH7709
This patch unifies the cpu specific interrupt setup code for sh7706, sh7707, sh7708 and sh7709 and moves the code into a new file called setup-sh770x.c. It makes sense to share the setup code between these processors because most hardware blocks are identical from a software point of view. With this patch the sh770x processors now have a complete set of vectors that match with the information provided by the data sheets. This is a big improvement for sh7708. Vectors for IRQ4 and IRQ5 are enabled by default. Use plat_irq_setup_pins() if pins IRQ0-3 should be used in IRQ mode. This patch also unifies the platform device setup code which means that the rtc driver now has platform data for all sh770x processors.
