meta-ostro-bsp: fix the incorrect device name for IIO device SI7020

When load the driver using the below command:
echo si7020 0x40 > /sys/bus/i2c/devices/i2c-0/new_device

In sysfs, the i2c name is si7020, however the iio name is 0-0040,
they are inconsistent. With this patch,
the iio name will be the same as the i2c device name

Fixes: IOTOS-1585
