x86_64: Change PMDS invocation to single macro

Very old binutils (2.12.90...) seem to have trouble with newlines
in assembler macro invocation. They put them into the resulting
argument expansion. In this case this lead to a parse error because
a .rept expression ended up spread over multiple lines. Change the PMDS()
invocation to a single line.
