initramfs: prevent initramfs printk message being split by messages from other code.
initramfs uses printk without a linefeed, then does some work, then uses
printk to finish the message off. However if some other code does a
printk in between, then the messages get mixed together. Better for each
message to be an independent line...
Example of problem that this fixes:
checking if image is initramfs...<7>Switched to high resolution mode on CPU 1
Switched to high resolution mode on CPU 0
it is
