Subject: efi/libstub: Add missing prototype for PE/COFF entry point
Patch-mainline: v5.8-rc1
Git-commit: 6e99d3213b10ee18428d6d20715ad6c0e89ead4d
References: jsc#SLE-16407
Fix a missing prototype warning by adding a forward declaration
for the PE/COFF entrypoint, and while at it, align the function
name between the x86 and ARM versions of the stub.
