docs: leds: convert to ReST

Rename the leds documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

-Kernel driver lp3944
-====================
-
-  * National Semiconductor LP3944 Fun-light Chip
-    Prefix: 'lp3944'
-    Addresses scanned: None (see the Notes section below)
-    Datasheet: Publicly available at the National Semiconductor website

-Description
------------
-The LP3944 is a helper chip that can drive up to 8 leds, with two programmable
-DIM modes; it could even be used as a gpio expander but this driver assumes it
-is used as a led controller.
-
-The DIM modes are used to set _blink_ patterns for leds, the pattern is
-specified supplying two parameters:
-  - period: from 0s to 1.6s
-  - duty cycle: percentage of the period the led is on, from 0 to 100
-
-Setting a led in DIM0 or DIM1 mode makes it blink according to the pattern.
-See the datasheet for details.
-
-LP3944 can be found on Motorola A910 smartphone, where it drives the rgb
-leds, the camera flash light and the lcds power.
-
-
-Notes
------
-The chip is used mainly in embedded contexts, so this driver expects it is
-registered using the i2c_board_info mechanism.
-
-To register the chip at address 0x60 on adapter 0, set the platform data
-according to include/linux/leds-lp3944.h, set the i2c board info:
-
-	static struct i2c_board_info a910_i2c_board_info[] __initdata = {
-		{
-			I2C_BOARD_INFO("lp3944", 0x60),
-			.platform_data = &a910_lp3944_leds,
-		},
-	};
-
-and register it in the platform init function
-
-	i2c_register_board_info(0, a910_i2c_board_info,
-			ARRAY_SIZE(a910_i2c_board_info));
