chore: drop console ttyS0 argument
Drop `console=ttyS0` argument for metal images/installer. `console=ttyS0` causes lot of issues with bare metal hardware when trying to use a physical serial port. Ref: * https://bugzilla.redhat.com/show_bug.cgi?id=1839923 * https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763601;msg=17 * https://www.kernel.org/doc/html/latest/admin-guide/serial-console.html * https://github.com/coreos/fedora-coreos-tracker/issues/567 Fixes: #8695 Fixes: #8657 Fixes: #8127 Signed-off-by: Noel Georgi <git@frezbo.dev>
