    sh: intc - convert voyagergx code · 48180cab
    Magnus Damm authored
    This patch converts the sh-specific voyagergx interrupt code to make use
    of intc. A lot of "interesting" old cruft gets replaced with intc tables
    and some simple demux code.
    
    - All interrupt sources in the sm501 data sheet are now in the header.
    - The number and order of IRQ values are disconnected from register bits.
    - Interrupt sources now start from IRQ 200.
    - set_irq_chained_handler() is now used to hook up the demux function.
    
    In the future it would probably make sense to move the interrupt demuxer
    into into the mfd driver, but this is probably a nice step in the right
    direction until that happens.
    
    Tested on a R2D-1 board using the serial port hooked up to the sm501.
