Hi,

This patchset addresses the following two warnings on microTVM:

[0]

[...]
/home/gromero/git/tvm/python/tvm/micro/contrib/zephyr.py:391: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
  doc = yaml.load(f)
[...]

[1]

[...]
/home/gromero/git/tvm/python/tvm/target/target.py:460: UserWarning: tvm.target.create() is being deprecated. Please use tvm.target.Target() instead
  warnings.warn("tvm.target.create() is being deprecated. Please use tvm.target.Target() instead")
[...]

Warning [0] is related to the deprecated form (no loader specified) of yaml.load(input), while the second one is related to the use of deprecated tvm.target.create().

Both warnings appear when running micro_tflite.py. The first one [0] when TARGET = tvm.target.target.micro("stm32f746xx") and the second one [1] when TARGET = tvm.target.target.micro("host"), which is the default target.

Thanks for contributing to TVM! Please refer to guideline https://tvm.apache.org/docs/contribute/ for useful information and tips. After the pull request is submitted, please request code reviews from Reviewers by @ them in the pull request thread.

Specify the loader to be used by yaml.load as the current form used without
specifying explicitly a loader is deprecated since PyYAML 5.1 and will
throw a noisy warning.

Avoid using tvm.target.create as it's deprecated and use
tvm.target.Target directly instead.

@areusch Hi. Could you review that small patchset, please? For warning [0] I'm assuming microTVM is not locked with any old PyYAML version (i.e. < 5.1). If it's locked we could simply silence the warning, which is not so nice I think. Thanks!
