soc/amd/mendocino: Print content of manifest file
This adds printing content of 'manifest' file at ramstage.
It allows to learn about blobs version used to build the coreboot
binary, which is useful when investigating bugs.
Version data are stored in CBFS file, which was generated during
coreboot build. If AMD FW blobs will be manually replaced in coreboot
image, versions from CBFS file are no longer valid.
Log:
AMDFW blobs version:
type: 0x01 ver:00.3c.01.18
type: 0x08 ver:00.5a.28.00
type: 0x30 ver:2b.25.b0.10
type: 0x73 ver:00.3c.01.18
BUG=b:224780134
TEST=Tested on Skyrim device
