MAINLINE pinmux:exynos:uart:fix: Add default statement to remove warnings (gcc-4...

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]
