nmk_pinctrl_probe() iterates over each GPIO block. Use an early
conditional continue to skip to the next iteration rather than indent
all the loop code block.

Do not change code logic. The block is changed from:

	for (i = 0; i < NMK_MAX_BANKS; i++) {
		x = of_parse_phandle(...);
		if (x) {
			... do work ...
		}
	}

To:

	for (i = 0; i < NMK_MAX_BANKS; i++) {
		x = of_parse_phandle(...);
		if (!x)
			continue;

		... do work ...
	}
