Rebecca Cran 8ba392687b OvmfPkg: Update code to be more C11 compliant by using __func__
__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.

Since it's more standard, replace __FUNCTION__ with __func__ throughout
OvmfPkg.

The kernel will be instructed via its command line to load the initrd from
