vc/amd/fsp/picasso: replace #pragma pack(1) with __packed attribute 

Forgetting to add the #pragma pack() at the end of the header file can
lead to hard to debug breakage, so get rid of the #pragma pack usage and
add a __packed to the structs that need to be packed which has less
possibly unwanted side effects.

Since commit d44221f9c8 coreboot always
includes commonlib/compiler.h which provides __packed.

TEST=Timeless build results in identical binary.
