ANDROID: x86/cpu/vmware: use the full form of inl in VMWARE_PORT

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
