[PATCH v3 0/2] core: ofnode: add of_graph parsing helpers

[Svyatoslav Ryhel]

Add a mostly complete list of ofnode analogs of of_graph
parsing helpers.

Commits pass all tests of stage 1 and all but sandbox_spl test of stage 2.
I am not able to track how these commits affect spl, log does not provide
any references to ofnode_graph testes or functions

Here is a link to latest test: https://source.denx.de/u-boot/custodians/u-boot-tegra/-/jobs/1028134

---
Changes in v3:
- fixed missing reg property
- switched to ut_asserteq_str and ofnode_has_property

Changes in v2:
- added tests
