The intc tables for sh3 currently contain a typo where the bit
fields in IPRD are mixed up for IRQ4 and IRQ5. This patch makes
sure the correct bit fields are used - all according to the
datasheets.

This patch converts the cpu specific interrupt setup code for
sh7705 from ipr to intc. While at it new vectors are added to
match the information provided by the datasheet.
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 adds sh7705 specific platform data for the rtc driver.

This patch unifies the cpu specific interrupt setup functions for
interrupt controller blocks such as ipr, intc2 and intc. There is no
point in having separate functions for each interrupt controller, so
let's clean this up.

This patch reworks the ipr code by grouping the offset array together
with the ipr_data structure in a new data structure called ipr_desc.
This new structure also contains the name of the controller in struct
irq_chip. The idea behind putting struct irq_chip in there is that we
can use offsetof() to locate the base addresses in the irq_chip
callbacks. This strategy has much in common with the recently merged
intc2 code.
One logic change has been made - the original ipr code enabled the
interrupts by default but with this patch they are all disabled by
default.

This fixes up SH7705 CPU support and the SE7705 board
for some of the recent changes.

This adds some simple setup code for most of the CPU subtypes,
primarily simple platform device registration.
