Currently the class type of igd_lpc bridge PCI device is not initialized.
In such case the guest driver doesn't detect the platform correctly when it
is in GVT-d mode. Then the linux i915 driver can't work.

Intel Graphics Device(IGD) passthrough on Windows guest
has the restriction that it need a lpc bridge device
located in 00:1f.0 PCI slot.
This patch add an extra lpc class for this restriction,
the lpc class will be used to create a dummy lpc bridge.
To enable gvt-d GOP driver work,
the VID, DID, REVID, SUBVID, SUBDID of igd-lpc
need aligned with physical one.

Make uart_init and uart_deinit internal functions. And make
uart_set_backend/uart_release_backend cover uart_init/uart_deinit
function.
This will make mevent teardown callback adding easier for uart_core.

The lpc dm causes that UOS can't boot if the parameters are set incorrectly,
it is not friendly to users.
This patch optimizes the lpc error handle flow. UOS always can boot successfully
whatever the lpc settings are.
