Input: da9055_onkey - remove use of regmap_irq_get_virq()

Using platform_get_irq_byname() to retrieve the IRQ number returns the
VIRQ number rather than the local IRQ number for the device.  Passing that
value then into regmap_irq_get_virq() causes a failure because the
function is expecting the local IRQ number (e.g.  0, 1, 2, 3, etc).

This patch removes use of regmap_irq_get_virq() to prevent this failure
from happening.
