Squashed with:

rockchip/rk3399: Halt if we get an invalid odt or drv value

When we were pushing the updated sdram.c to coreboot.org, the compiler
there found that we were not initializing vref_value_dq in all code
possible code paths.

This patch updates those code paths to halt the system.

Branch=none
Bug=none
Test=Built with coreboot.org toolchain and verified that the compile
errors were gone.
