Lad, Prabhakar d3422a18db gpio: davinci: remove unused variable intc_irq_num
As the davinci-gpio driver is migrated to use irqdomain
there is no need to pass the irq base for the gpio driver.
This patch removes this variable from davinci_gpio_platform_data
and also the refrences from the machine file.
