Paolo Bonzini c0825c63cf libqos: convert I2C to qgraph
Create an i2c-bus interface, corresponding to the I2CAdapter struct.
Wrap IMXI2C and OMAPI2C with a QOSGraphObject, and add the get_driver
function to retrieve the I2CAdapter.

The conversion is still not complete; for simplicity, i2c_recv and
i2c_send (along with their wrappers) still take an adapter/address
pair.  Fixing that would be complicated until the tests are converted
to qgraph, so it is left for after the conversion.

Paolo Bonzini 732c919cf0 libqos: split I2CAdapter initialization and allocation
Provide *_init functions that populate an I2CAdapter struct without
allocating one, and make the existing *_create functions wrap them.

Because in the new setup *_create might return a pointer inside the
IMXI2C or OMAPI2C struct, create companion *_free functions to go
back to the outer pointer.

All this is temporary until allocation will be handled entirely by
qgraph.

Paolo Bonzini e8ecb706a8 libqos: move common i2c code to libqos
The functions to read/write 8-bit or 16-bit registers are the same
in tmp105 and pca9552 tests, and in fact they are a special case of
"read block"/"write block" functionality; read block in turn is used
in ds1338-test.

Move everything inside libqos-test, removing the duplication.  Account
for the small differences by adding to tmp105-test.c the "read register
after writing" behavior that is specific to it.

Cédric Le Goater 5141d4158c misc: add pca9552 LED blinker model
Specs are available here :

    https://www.nxp.com/docs/en/application-note/AN264.pdf

This is a simple model supporting the basic registers for led and GPIO
mode. The device also supports two blinking rates but not the model
yet.

Eric Blake f1dfd50732 libqos: Use explicit QTestState for i2c operations
Drop one more client of global_qtest by teaching all i2c test
functionality to pass in an explicit QTestState, adjusting all
callers.

Jean-Christophe Dubois 7f3986278b i.MX: Add qtest support for I2C device emulator.
This is using a ds1338 RTC chip on the I2C bus. This RTC chip is
not present on the real 3DS PDK board.
