        src/sys/arch/arm/broadcom: bcm2835_bsc.c
        src/sys/arch/arm/nvidia: tegra_i2c.c

Log Message:
If we don't get informed (via device properties) of child I2C devices,
don't assign an empty array to iba.iba_child_devices, as it will prevent
indirect configuration of the I2C bus from occurring.

Tested on Raspberry Pi (bcm2835), identical logical fix replicated
(and compile-tested) elsewhere.
