F_CLOCK changed to F_USB to be more descriptive, and applicable on future architecture ports.

* \section Sec_F_CLOCK The F_CLOCK Parameter
* \section Sec_F_USB The F_USB Parameter
* This parameter indicates the target AVR's input clock frequency, in Hz. This is the actual clock input, before any prescaling is performed. In the
* USB AVR architecture, the input clock before any prescaling is fed directly to the PLL subsystem, and thus the PLL is derived directly from the
* clock input. The PLL then feeds the USB and other sections of the AVR with the correct upscaled frequencies required for those sections to function.
