mfd: Fix asic3_gpio_to_irq
Assumption that irq numbers of asic3 gpios start at
IRQ_BOARD_START is certainly wrong - driver may as well
use any other base for its irqs (consider for example
the imaginary case of two ASIC3 chips onboard)
Furthermore, some platforms even don't have IRQ_BOARD_START
defined, so driver will fail to build on them:
-------------------------------------------------------
drivers/mfd/asic3.c: In function 'asic3_gpio_to_irq':
drivers/mfd/asic3.c:530: error: 'IRQ_BOARD_START' undeclared (first use in this function)
drivers/mfd/asic3.c:530: error: (Each undeclared identifier is reported only once
drivers/mfd/asic3.c:530: error: for each function it appears in.)
-------------------------------------------------------
Fix it by using irq_base from driver data.
