[U-Boot] [PATCH v1] test: py: Add an option to skip sleep test

[Michal Simek]

Some QEMUs have a problem with time setup that's why
sleep test is failing. Introduce env__sleep_accurate
boardenv variable to have an option to skip sleep test.

Changes in v1:
- Change subject line and patch description
- Move from RFC to regular patch
