[Nexthop][m4062nhp] Add bsp_tests config

**Pre-submission checklist**
- [x] I've ran the linters locally and fixed lint errors related to the
files I modified in this PR. You can install the linters by running `pip
install -r requirements-dev.txt && pre-commit install`
- [x] `pre-commit run`

** Summary
Add a bsp_tests.json for the m4062nhp platform and load it in the
config_lib BspTests coverage. The config describes the two ADM1266
power-sequencers (SCM.DPM / SCM.DPM_2: vout1..vout17 hwmon features and
the PMBus revision register) and the TMP464 switch-card temp sensor
(SMB.SWITCH_CARD_TEMP_SENSOR: temp1..temp5 hwmon features and the
manufacturer/device ID registers).

** Test Plan
Exercise it from ConfigLibTest to verify the file in a config-load test.
