952f525af5 Provide a way for a peripheral to query its clock frequency 
Currently this looks up the frequency in the global singleton that must
be initialized by the per-chip RCC implementation. At present, this is
only done for the L0 family of chips.

edec5833b3 Refactor SPI and fix write bug 
* SPI write v2 was hanging in write due to an infinite loop
* SPI word write was not followed by a read back

The u8 and u16 write/read logic have been refactored into write_word and
read_word.
