bootloader: add specific boot cmdline options for Raspberry Pi serial console
console=ttyS0,115200 will work on Raspberry Pi 3.
Raspberry Pi 2 does not boot without console=tty1 on cmdline.
To have console output on both serial port and HDMI display,
8250.nr_uarts=1 is needed.
On Raspberry Pi 2, though, it is required to edit /boot/extlinux/extlinux.conf
to use ttyAMA0 instead of ttyS0 in the console parameter.
