sh: intc - convert voyagergx code
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. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
