[PATCH] Documentation: gpio: correct platform data section

[Vivien Didelot <vivien.didelot@xxxxxxxxxxxxxxxxxxxx>]

The GPIO_LOOKUP_IDX macro has no dev_id parameter. Remove it from the
examples and move the dev_id description under the gpiod_lookup_table
example, where it belongs.

The gpio_lookup_flags are prefixed GPIO_, not GPIOF_. So correct the
flag list, and also add GPIO_ACTIVE_HIGH.

Finally rename the board.txt documentation file to machine.txt, to be
consistent with the related include/linux/gpio/machine.h file, similar
to the regulator files.

 GPIOs are mapped by the means of tables of lookups, containing instances of the
 gpiod_lookup structure. Two macros are defined to help declaring such mappings:
 
-	GPIO_LOOKUP(chip_label, chip_hwnum, dev_id, con_id, flags)
-	GPIO_LOOKUP_IDX(chip_label, chip_hwnum, dev_id, con_id, idx, flags)
+	GPIO_LOOKUP(chip_label, chip_hwnum, con_id, flags)
+	GPIO_LOOKUP_IDX(chip_label, chip_hwnum, con_id, idx, flags)
 
 where
 
   - chip_label is the label of the gpiod_chip instance providing the GPIO
   - chip_hwnum is the hardware number of the GPIO within the chip
-  - dev_id is the identifier of the device that will make use of this GPIO. It
-	can be NULL, in which case it will be matched for calls to gpiod_get()
-	with a NULL device.
   - con_id is the name of the GPIO function from the device point of view. It
 	can be NULL, in which case it will match any function.
   - idx is the index of the GPIO within the function.
   - flags is defined to specify the following properties:
-	* GPIOF_ACTIVE_LOW	- to configure the GPIO as active-low
-	* GPIOF_OPEN_DRAIN	- GPIO pin is open drain type.
-	* GPIOF_OPEN_SOURCE	- GPIO pin is open source type.
+	* GPIO_ACTIVE_HIGH	- to configure the GPIO as active-high
+	* GPIO_ACTIVE_LOW	- to configure the GPIO as active-low
+	* GPIO_OPEN_DRAIN	- GPIO pin is open drain type.
+	* GPIO_OPEN_SOURCE	- GPIO pin is open source type.
 
 In the future, these flags might be extended to support more properties.
