mec15xxevb_assy6853:region `SRAM' overflowed during build

[maksimmasalski]

Describe the bug
Can't build test tests/portability/cmsis_rtos_v2/ using west or sanitycheck I receive error that SRAM overflowed.

To Reproduce
Steps to reproduce the behavior:

1. west build -p -b mec15xxevb_assy6853 tests/portability/cmsis_rtos_v2/
   or
2. sanitycheck --hardware-map ~/mec1.file --device-testing -T tests/portability/cmsis_rtos_v2/ -vv
3. See error

Expected behavior
Test should be build and passed for the Microchip.

Impact
Can't execute that test

@scottwcpg Do you have any thoughts about that?

[nashif]

this is not a bug, the test/sample just does not fit on the device.
