rockchip: puma-rk3399: remove dead code

CONFIG_SERIAL_TAG is not selectable for ARM64 machines. While
get_board_serial is weakly defined if ENV_VARS_UBOOT_RUNTIME_CONFIG is
defined, it is only called when CONFIG_SUPPORT_PASSING_ATAGS is defined,
which also is not selectable for ARM64 machines. Therefore this is dead
code so let's remove it.
