test-case: add new test case for soc power measurement

Intel SoCWatch is proprietary tool to measure with energy analsis for
Intel platofrm. With socwatch, plan to check package C-State and
average package power number etc.

+## Case Name: check-soc-power-status
+## Preconditions:
+## Intel SoCwatch tool must be installed on the device
+## Description:
+## Run the socwatch command to check SoC power status
+## Test steps:
+## 1. load socwatch kernel module
+## 2. run socwatch command with desired parameters
+## 3. check return value from socwatch
+## 4. collect logs
+## 5. check dmesg errors
+## 6. unload socwatch kernel module
+## Expect result:
+## consistent power status across tests
+## check kernel log and find no errors
+##
