Revert "Documentation: kernel-parameters: Add DEVNAME:0.0 format for serial ports"

This reverts commit 5c3a766e9f057ee7a54b5d7addff7fab02676fea.

Let's roll back all of the serial core and printk console changes that
went into 6.10-rc1 as there still are problems with them that need to be
sorted out.

-		<DEVNAME>:<n>.<n>[,options]
-			Use the specified serial port on the serial core bus.
-			The addressing uses DEVNAME of the physical serial port
-			device, followed by the serial core controller instance,
-			and the serial port instance. The options are the same
-			as documented for the ttyS addressing above.
-
-			The mapping of the serial ports to the tty instances
-			can be viewed with:
-
-			$ ls -d /sys/bus/serial-base/devices/*:*.*/tty/*
-			/sys/bus/serial-base/devices/00:04:0.0/tty/ttyS0
-
-			In the above example, the console can be addressed with
-			console=00:04:0.0. Note that a console addressed this
-			way will only get added when the related device driver
-			is ready. The use of an earlycon parameter in addition to
-			the console may be desired for console output early on.
