leds-lp5521: modify the way of setting led device name
Currently the led device name is fetched from the device_type in
I2C_BOARD_INFO which comes from the platform data. This name is in turn
used to create an entry in sysfs.
If there exists two or more lp5521 on a particular platform, the
device_type in I2C_BOARD_INFO has to be the same, else lp5521 driver probe
wont be called and if used so, results in run time warning "cannot create
sysfs with same name" and hence a failure.
The name that is used to create sysfs entry is to be passed by the struct
led_platform_data. Hence adding an element of type const char * and
change in lp5521 driver to use this name in creating the led device if
present else use the name obtained by I2C_BOARD_INFO.
