tests: Add tests to read from chip

Two tests cover the code which performs do_read operation.

First one works with fake chip and dummy programmer. Fake chip has all
operations defined, and a buffer to emulate chip memory.

Second one uses the chip which is closer to the real one, because
read/write/unlock/erase operations are real. The tests takes the
advantage of dummyflasher's capability of emulating a W25Q128.V chip.
