Subject: [PATCH] gpio: regmap: fix type clash

GPIO_REGMAP_ADDR_ZERO() cast to unsigned long but the actual config
parameters are unsigned int. We use unsigned int here because that is
the type which is used by the underlying regmap.

Fixes: ebe363197e52 ("gpio: add a reusable generic gpio_chip using regmap")
