leds: rt8515: Add Richtek RT8515 LED driver This adds a driver for the Richtek RT8515 dual channel torch/flash white LED driver. This LED driver is found in some mobile phones from Samsung such as the GT-S7710 and GT-I8190. A V4L interface is added. We do not have a proper datasheet for the RT8515 but it turns out that RT9387A has a public datasheet and is essentially the same chip. We designed the driver in accordance with this datasheet. The day someone needs to drive a RT9387A this driver can probably easily be augmented to handle that chip too. Sakari Ailus, Pavel Machek and Andy Shevchenko helped significantly in getting this driver right.

This option enables support for the RT4505 flash LED controller.
RT4505 includes torch and flash functions with programmable current.
And it's commonly used to compensate the illuminance for the camera
inside the mobile product like as phones or tablets.

leds: rt8515: add V4L2_FLASH_LED_CLASS dependency The leds-rt8515 driver can optionall use the v4l2 flash led class, but it causes a link error when that class is in a loadable module and the rt8515 driver itself is built-in: ld.lld: error: undefined symbol: v4l2_flash_init >>> referenced by leds-rt8515.c >>> leds/flash/leds-rt8515.o:(rt8515_probe) in archive drivers/built-in.a Adding 'depends on V4L2_FLASH_LED_CLASS' in Kconfig would avoid that, but it would make it impossible to use the driver without the v4l2 support. Add the same dependency that the other users of this class have instead, which just prevents the broken configuration.
