First set of Counter fixes for 6.6

Browse Source 
The counter_get_ext() function would incorrectly refer to the first
 element of the extensions array to handle component array extensions
 when they are located at a different index; a fix is provided to index
 to the correct element in the array for this case. A fix for the
 microchip-tcb-capture is provided as well to correct an inverted
 internal GCLK logic for clock selection.
