[PATCH 5/9] clk: si5341: Update initialization magic

[Robert Hancock <robert.hancock@calian.com>]

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")
