soc/amd: Move psp_transfer.h out of each SOC into common

The psp_transfer.h file was the same under all SoCs, and is really
tied to the file common/vboot/transfer.c, not the SOC.

This patch makes an include directory under vboot to put the header into
and sets it to be included for all SoCs using SOC_AMD_COMMON. This makes
the header file available to all platforms, so that new chips that don't
use the psp_verstage don't have to make a psp_transfer.h file just to
satisfy the compiler.
