This series consists of fixes for DTC warnings and improvements of
the GPIO labels. So this is nothing critical, but helpful
in case CONFIG_GPIO_SYSFS is disabled.

Compiling the bcm283x DTS with W=1 leads to the following warning:
Warning (unit_address_vs_reg): /memory: node has a reg or ranges property,
but no unit name
Fix this by adding the unit address.

According to the schematics for all RPis with a 40 pin header,
the GPIOs 0 and 1 are labeled as ID_SD and ID_SC. In order to
clarify that is a I2C bus, append the third letter.

The RPI 3 B+ provides control to both LEDs (PWR and ACT). So append
the first letter of the LED color (like in the schematics) in order
to clarify this.

The GPIO sysfs is deprecated and disabled in the defconfig files.
So in order to motivate the usage of the new GPIO character device API
add the missing GPIO line names for Raspberry Pi 2 and 3. In the lack
of full schematics i would leave all undocumented pins as unnamed.
