[U-Boot] [PATCH v2 1/1] lib/display_options: Fix print_freq

[Suriyan Ramasami]

Build without CONFIG_SPL_SERIAL_SUPPORT does not print the cpu freq.
Booting an odroid U3 board, one sees this:
CPU:   Exynos4412 @ GHz
instead of:
CPU:   Exynos4412 @ 1 GHz

This change was done to get rid of compiler warnings related to the
unused variable 'n' when CONFIG_SPL_SERIAL_SUPPORT is not defined in an
SPL build. Example board: smartweb

v2:
* Get rid of variable 'n' altogether

v1:
* Remove #ifdef CONFIG_SPL_SERIAL_SUPPORT
