x86/cpu/vmware: Use the full form of INL in VMWARE_PORT
LLVM's assembler doesn't accept the short form INL instruction:
inl (%%dx)
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.
