Increase SPC threshold for little and mid cores for CAMERA_STREAMING_STANDARD

SPC threshold is too low for both Little and Mid cores. This CL increases this
threshold to 55 for Little Core and to 30 for Mid core.
Test results show lower framedrop rate in presence of background load,
without having a negative impact on the power.
