[RFC PATCH 05/10] sh: intc: remove dependency on NR_IRQS

[Rob Herring]

From: Rob Herring <rob.herring at calxeda.com>

SH intc has a compile time dependency on NR_IRQS. Make this dependency a
local define so that shmobile (and ARM in general) can have run-time
NR_IRQS setting. SH has NR_IRQS set to 512 and shmobile has NR_IRQS set to
1024, so we are using the maximum.
