Subject[PATCH] x86/cpu/vmware: use the full form of inl in VMWARE_PORT
From
LLVM's assembler doesn't accept the short form inl (%%dx) instruction,
but instead insists on the output register to be explicitly specified:

<inline asm>:1:7: error: invalid operand for instruction
inl (%dx)
^
LLVM ERROR: Error parsing inline asm

Use the full form of the instruction to fix the build.
