accel/ivpu: Implement D0i2 disable test mode

Browse source 
Add power_profile firmware boot param and set it to 0 by default
which is default FW power profile.

Implement IVPU_TEST_MODE_D0I2_DISABLE which is used for setting
power profile boot param value to 1 which prevents NPU from entering
d0i2 power state.
