For Exynos' pinmux UART implementation there was a possibility to run
for() statement with uninitialized bank, start and count values.
Those warnings appear when following toolchain is used
(gcc-4.8.2-glibc-2.18-binutils-2.24):
warning: 'count' may be used uninitialized in this function
[-Wmaybe-uninitialized]
