Subject: [PATCH v2 0/2] x86/purgatory: Fix sparse warnings

Sparse emits multiple warnings of type 'symbol was not declared'.

Separate fixes into two patches. In first patch add static keyword
to functions and variables which have file scope only.

In the second patch add a header file with the function declaration.
Include the header file in the C source file defining the function
in order to fix the sparse warning. Include the header file in ASM
file containing the call site thereby adding documentation of usage.
