Improve IRQ triggering support by making use of the macro
INTC_IRQ_PINS_32() for INTCA on sh73a0. Unfortunately it
is not as easy as just using the macro as-is, we need to
do mask and unmaks in the GIC but configure other bits
and ack in INTCA. Update GPIO IRQ mappings while at it.

This patch adds support for sh73a0 GPIO IRQs by making use
of the PFC GPIO IRQ feature. Only IRQ pins are  supported
at this time. In the future when PINT interrupts also are
supported properly we can easily extend the table with such
information. Also, the sh73a0 is currently making use of
the GIC for external interrupt which is rather unflexible
when it comes to triggering configuration at this point.

Always use CS0 shadow area for NOR flash instead of regular CS0
memory area on ap4evb.

When booting from CS0 NOR Flash the regular CS0 memory area is
available, but when booting via USB the MASK ROM gets mapped to
0x0 which gets in the way for the NOR Flash. Always using CS0
shadow area works well for both NOR Flash boot and USB boot.

Problem comes from commit 0e734419
(ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.)

If inet_csk_route_child_sock() returns NULL, we should release socket
lock before freeing it.

Another lock imbalance exists if __inet_inherit_port() returns an error
since commit 093d2823 ( tproxy: fix hash locking issue when using
port redirection in __inet_inherit_port()) a backport is also needed for
>= 2.6.37 kernels.

Returning the max traffic classes on get requests simplifies
user space configurations because applications will know

Typical switch implementations use 2 or 3 traffic classes
