pinctrl: exynos: fix type of count integer
unsigned int count is used to capture return of dev_read_string_count.
When an error occurs dev_read_string_count returns -ve, which can
hence not be handled correctly. Use int instead of unsigned int so
that errors are detected.
Fixes: 16ca80adc551 ("pinctrl: Add pinctrl driver support for Exynos7420 SoC")
