SAM3/4 Timer: Remove broken definitions for BMR register.

Browse Source 
Per documentation SAM4S and SAM4E have the BMR register values
as they are already defined. No need for chip specific values.

In addition:
 - CONFIG_ARCH_CHIP_SAM4s has wrong lower case 's' so the definitions would
   not be used anyways for SAM4S builds.
 - TC_BMR_TC2XC2S_TIOA2 does not make sense. There is no way to loop back
   TC2's TIOA2 into itself.
