This series contains some random trivial cleanups I came across when working on
the PC machines. It consists of reducing the usage of global variables and
eliminating some redundancies.

Testing done:
* `make check`
* `qemu-system-x86_64 -M q35 -m 2G -cdrom \
   manjaro-kde-21.3.2-220704-linux515.iso`
* `qemu-system-x86_64 -M pc -m 2G -cdrom manjaro-kde-21.3.2-220704-linux515.iso`

  hw/i386/ich9: Rename Q35_MASK to ICH9_MASK
  hw/i386/pc_q35: Resolve redundant q35_host variable
  hw/i386/pc_{q35,piix}: Reuse MachineClass::desc as SMB product name
