[PATCH] i2c: brcmstb: Fixed adapter named with optional interrupts

[Florian Fainelli <f.fainelli@gmail.com>]

When the adapter is registered without interrupts, we would be showing
the following:

  # i2cdetect -l
  i2c-3   i2c             Broadcom STB :                          I2C adapter

which is visually disturbing, only add the separator if we do have an
interrupt.

Fixes: dd1aa2524bc5 ("i2c: brcmstb: Add Broadcom settop SoC i2c controller driver")
