Alexander Sverdlin d41d547a41 MIPS: octeon: Fix GPIO number in IRQ chip private data
Current GPIO chip implementation in octeon-irq is still broken, even after upstream
commit 87161ccdc6 (MIPS: Octeon: Fix broken interrupt
controller code). It works for GPIO IRQs that have reset-default configuration, but
not for edge-triggered ones.

The problem is in octeon_irq_gpio_map_common(), which passes modified "hw" variable
(which has range of possible values 16..31) as "gpio_line" parameter to
octeon_irq_set_ciu_mapping(), which saves it in private data of the IRQ chip. Later,
neither octeon_irq_gpio_setup() is able to re-configure GPIOs (cvmx_write_csr() is
writing to non-existent CVMX_GPIO_BIT_CFGX), nor octeon_irq_ciu_gpio_ack() is able
to acknowledge such IRQ, because "mask" is incorrect.

Fix is trivial and has been tested on Cavium Octeon II -based board, including
both level-triggered and edge-triggered GPIO IRQs.
