drivers/misc/lis3lv02d/lis3lv02d_i2c.c: add lis3lv02d device tree init

Add lis3lv02d device tree initialization code/API to take pdata from
device node.  Also adds device tree init matching table support to
lis3lv02d_i2c driver.  If the driver data is passed from device tree, then
this driver picks up platform data from device node through common/generic
lis3lv02d.c driver.
