[ARM] 3192/1: Remove gpio_isr_line_clear() API from IXP4xx
Patch from Deepak Saxena Other than interrupt masking purposes, this API is only used when configuring interrupt lines and this patch moves that functionality directly into the ixp4xx_set_irq_type() implementation as board level PCI code should not need to worry about those details.
