cpu/intel/car: Define post codes
This moves a lot of post code values, but unifies them between
platforms, so that the same value means the same thing as much as
possible.
The P4-netburst code was the most extensive and most different, so that
dictated the majority of the values. Three were two values there that
didn't match the other files, so those two values, 0x22 & 0x29 have
duplicate entries in the table.
The rest of the entries are similar between platforms, though the values
for many of them were moved to match the P4-netburst values.
POST_BOOTBLOCK and POST_POSTCAR values are intended to eventually become
global, while POST_SOC would be specific to the Intel platforms.
