[PATCH] gpio: bcm-kona: fix bcm_kona_gpio_reset() warnings

[Ben Dooks]

The bcm_kona_gpio_reset() calls bcm_kona_gpio_write_lock_regs()
with what looks like the wrong parameter. The write_lock_regs
function takes a pointer to the registers, not the bcm_kona_gpio
structure.

Fix the warning, and probably bug by changing the function to
pass reg_base instead of kona_gpio, fixing the following warning:

drivers/gpio/gpio-bcm-kona.c:550:47: warning: incorrect type in argument 1 (different address spaces)
drivers/gpio/gpio-bcm-kona.c:550:47:    expected void [noderef] <asn:2>*reg_base
drivers/gpio/gpio-bcm-kona.c:550:47:    got struct bcm_kona_gpio *kona_gpio
drivers/gpio/gpio-bcm-kona.c:554:47: warning: incorrect type in argument 1 (different address spaces)
drivers/gpio/gpio-bcm-kona.c:554:47:    expected void [noderef] <asn:2>*reg_base
drivers/gpio/gpio-bcm-kona.c:554:47:    got struct bcm_kona_gpio *kona_gpio
