clk: si5341: Update initialization magic
Update the default register settings to include the VCO_RESET_CALCODE
settings (set by the SiLabs ClockBuilder software but not described in
the datasheet). Also update part of the initialization sequence to match
ClockBuilder and the datasheet.
Fixes: 3044a860fd ("clk: Add Si5341/Si5340 driver")
