[oe] [meta-yocto][PATCH] meta-yocto-bsp: replace deprecated "SERIAL_CONSOLE"

[Maciej Pijanowski]

SERIAL_CONSOLE was already deprecated in 2013, yet still some
machine configuration files were using it. This patch replaces
it with SERIAL_CONSOLES, which is the successor.

The documentation seems to be already up do date.
beaglebone-yocto.conf in the bsp-guide already uses
SERIAL_CONSOLES. The ref-manual redirects from SERIAL_CONSOLE
to SERIAL_CONSOLES.

[YOCTO #12653]
