vendorcode/amd/agesa/f16kb: Update Kabini PI from v1.0.0.0 to v1.0.0.7
The platform initialization (PI) code v1.0.0.7 for Kabini has some
enhancements like ECC DIMM support, new CPU microcode rev 0700010B, FCH
bug fix (RTC) and so on.
Use the name Kabini instead of Kerala everywhere.
Note, the former PI code was indeed version v1.0.0.0 instead of v0.0.1.0
as used in `AGESA_VERSION_STRING`.
