pca953x: pca953x driver fixes for x86 mrst
Our Moorestown platform has two max7315 chips which is covered by pca953x i2c gpio driver. A while ago this driver got updated with nested irq thread support, and it broke the compatibity with "request_irq". For example, the gpio_keys.c driver can not work with this driver now. This patch fixes the issue by switching to generic_handle_irq. Also fix the irq_base issue: irq_base == 0 is valid, and a "-1" value should mean invalid. IRQ 0 is not a valid IRQ, irq_base of 0 is valid.
