src: Move POST_BOOTBLOCK_CAR to common postcodes and use it 

This moves the definition for POST_BOOTBLOCK_CAR from the intel-specific
postcodes into the common postcode list, and uses it for the
cache-as-RAM init as needed.

Because POST_BOOTBLOCK_CAR was set to 0x20 in some spots and 0x21 in
most of the others, the values were consolidated into 0x21.  This will
change the value on some platforms.

Any conflicts should get sorted out later in the conversion process.
