ARM: ARC: put sw_isr_table in ROM by default

Browse source 
We can save a great deal of RAM this way, it only needs to be
in RAM if dynamic interrupts are in use.

At some point this config option broke, probably when static
interrupts were introduced into the system.

To induce build (instead of runtime) errors when irq_connect_dynamic()
is used without putting the table in RAM, the dynamic interrupt
functions are now conditionally compiled.
