soc/amd/cezanne,picasso,sabrina: Fix incorrect values of CBFS amdfw position makefile variables
Currently apu/amdfw_a-position and apu/amdfw_b-position currently depend on CEZANNE_FW_A_POSITION and CEZANNE_FW_B_POSITION. This causes error messages from awk as these variables are sourced from fmap_config.h and these variables are expanded before fmap_config.h is built. However these variables should not be set to CEZANNE_FW_*_POSITION. These files end up in the FW_MAIN_* fmap regions. These regions are placed at the proper locations through the chromeos.fmd file. The apu/amdfw_*-position variables are the positions within these regions where the files end up. These variables should be set to 0x40 to coincide with the beginning of the FW_MAIN_* regions, accounting for the size of struct cbfs_file + filename + metadata, aligned to 64 bytes. Currently they end up in the correct locations only because fmap_config.h does not exist when the apu/amdfw_*-position variables are expanded.
This change explicity sets the value of these variables to 0x40, removing the errors from awk and ensuring that these files end up in the correct location in the resulting image. These changes are also applied to the Picasso and Sabrina makefiles as well.
BUG=b:198322933
TEST=Verified that the apu/amdfw_* files end up in the correct locations as reported by cbfstool during the build, did timeless builds and confirmed that coreboot.rom images were identical, tested AP firmware on guybrush and zork devices
