Mike Looijmans e8f127caf6 clk-si514, clk-si544: Implement prepare/unprepare/is_prepared operations
This adds prepare/unprepare/is_prepared functionality to the drivers for
the SI544 and SI514 chips, allowing the clock output to be disabled when
the clock is not in use.

Stephen Boyd d06e46c25a clk: si514: Migrate to clk_hw based OF and registration APIs
Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

Mike Looijmans 8ce20e6617 Add driver for the si514 clock generator chip
This patch adds the driver and devicetree documentation for the
Silicon Labs SI514 clock generator chip. This is an I2C controlled
oscillator capable of generating clock signals ranging from 100kHz
to 250MHz.
