The old value 0x3400 gave the INTCA and INTCS interrupt conrollers separated spaces, but required ARM support for more than 512 NR_IRQS which is not in place at this point. The value 0x2200 will make some of the INTCA interrupts make use of empty INTCS areas. This is a bit more error prone but works fine as a workaround for G3, G3 and AP4.

INTCS is the interrupt controller for the sh7372 SuperH processor core. It is tied into the INTCA interrupt controller which interfaces to the ARM processor. INTCS support is implemented using a new INTC table together with a chained interrupt handler that ties into the already supported INTCA controller.

Also use the generic DES header and remove the weak key check in 3DES mode, as RFC2451 mentions that the DES weak keys are not relevant for 3DES.
