Subject: [PATCH v1 05/10] MIPS: MT: Move "weak" from vpe_run() declaration
 to definition

When the "weak" attribute is on a declaration in a header file, every
definition where the header is included becomes weak, and the linker
chooses one definition based on link order (see 10629d711ed7 ("PCI: Remove
__weak annotation from pcibios_get_phb_of_node decl")).

Move the "weak" attribute from the declaration to the default definition so
we always prefer a non-weak definition over the weak one, independent of
link order.
