ARM: riscpc: use irq chip data in ecard.c
Use irq chip data to store the expansion card data pointer, rather than converting from the interrupt number to a slot number. This allows the interrupt chip methods to avoid knowing about interrupt numbering. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
