An earlier newline was missing and current print is from different task.
In this scenario flush the continuation line and store this line
seperatly.
This patch fix the below scenario of timestamp interleaving,
[ 28.154370 ] read_word_reg : reg[0x 3], reg[0x 4] data [0x 642]
[ 28.155428 ] uart disconnect
[ 31.947341 ] dvfs[cpufreq.c<275>]:plug-in cpu<1> done
[ 28.155445 ] UART detached : send switch state 201
[ 32.014112 ] read_reg : reg[0x 3] data[0x21]

boot_delay does not work for earlyprintk because the kernel cmdline
parsing is late.
Change to use early_param so early kernel messages can also be delayed.

This reports the names of consoles as they're being disabled to help
identify which is which during cut-over. Helps answer the question
"which boot console actually got activated?" once the regular console is
running, mostly when debugging boot console failures.

This patch guards the console_drivers list to be corrupted. The
for_each_console() macro insist on a strictly forward list ended by NULL:
con0->next->con1->next->NULL
Without this patch it may happen easily to destroy this list for example by
adding 'earlyprintk' twice, especially on embedded devices where the early
console is often a single static instance. This will result in the following
list:
con0->next->con0
This in turn will result in an endless loop in console_unlock() later on by
printing the first __log_buf line endlessly.
