ARM: exynos: Fix build error if SERIAL is disabled in SPL
If CONFIG_SPL_SERIAL_SUPPORT is not defined in include/configs/exynos5-common.h
the following error is produced during the build of the SPL:
arch/arm/mach-exynos/built-in.o: In function `do_lowlevel_init':
...u-boot/arch/arm/mach-exynos/lowlevel_init.c:221: undefined reference to `debug_uart_init'
Add additional condition to check if SPL build is in progress and
in that case check if CONFIG_SPL_SERIAL_SUPPORT is also set before
enabling the debug UART.
