Adding noAnalogWrite() function to disable PWM.
Also, removing the inline version of digitalPinToTimer() (since we're not optimizing the functions that use it anyway). The noAnalogWrite() function is in wiring_analog.c, deriving from the previous turnOffPWM() which has moved from wiring_digital.c. http://code.google.com/p/arduino/issues/detail?id=476

-// Forcing this inline keeps the callers from having to push their own stuff
-// on the stack. It is a good performance win and only takes 1 more byte per
-// user than calling. (It will take more bytes on the 168.)
-//
-// But shouldn't this be moved into pinMode? Seems silly to check and do on
-// each digitalread or write.
-//
-// Mark Sproul:
-// - Removed inline. Save 170 bytes on atmega1280
-// - changed to a switch statment; added 32 bytes but much easier to read and maintain.
-// - Added more #ifdefs, now compiles for atmega645
