console/post_codes: Add post codes for memory param prep callback

This change adds two new post codes to indicate start and end of
memory param preparation in callbacks to SoC/mainboard code:
1. 0x34: Start of memory preparation
2. 0x36: End of memory preparation

These post codes are already used in coreboot. This change just
ensures that the codes are defined in post_codes.h for easy lookup.

These post codes are useful if SoC/mainboard decides to do a reset of
the platform before returning back to memory initialization.
