Add BCM43438 (bluetooth) as a serdev slave device of uart0 (pl011/ttyAMA0).
This allows to automatically insert the bcm43438 to the bluetooth
subsystem instead of relying on patched userspace helpers (hciattach).
In order to keep a debug UART we need to switch to uart1.

Contrary to other RPi devices, RPi3 uses uart0 to communicate with
the BCM43438 bluetooth controller. uart1 is then used for the console.
Today, the console configuration is inherited from the bcm283x dtsi
(bootargs) which is not the correct one for the RPi3. This leads to
routing issue and confuses the Bluetooth controller with unexpected
data.
This patch introduces chosen/stdout path to configure console to uart0
on bcm283x family and overwrite it to uart1 in the RPi3 dts.
Create serial0/1 aliases referring to uart0 and uart1 paths.
Remove unneeded earlyprintk.

The Raspberry Pi Zero W has the same components like the Zero plus
a Cypress CYW43438 wireless chip (wifi + bl).
