[PATCH v3 6/7] gpio: ep93xx: refactor ep93xx_gpio_add_bank

[Nikita Shubin]

- replace plain numbers with girq->num_parents in devm_kcalloc
- replace plain numbers with girq->num_parents for port F
- refactor i - 1 to i + 1 to make loop more readable
- combine getting IRQ's loop and setting handler's into single loop

v2->v3
- use ->num_parents instead of ARRAY_SIZE()
