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.
