Arthur Heymans 2785c118a6 device/dram/ddr2.c: Improve error returning and debug output
This patch outputs decoding errors with BIOS_WARNING instead of
depending on CONFIG_DEBUG_RAM_SETUP.

Returns SPD_STATUS_INVALID on invalid settings for tRR, bcd and tCK
and doesn't try to create a valid setting if an invalid setting is
detected.
