[PATCH 0/5] OvmfPkg/QemuFwCfgLib: support the DMA-like interface

[Laszlo Ersek <lersek@redhat.com>]

I plan to use the DMA interface of QEMU's fw_cfg in upcoming features
(one short term, another long term).

The first four patches in the series refactor the current library
instances (and even the lib class) slightly, while the last patch adds
the feature to OVMF.

Branch: ovmf_fwcfg_dma
