panic() (as well as early_panic() in arm) is inconsistently called with or
without a trailing newline. This results in cases where the lower line of
*****s is not on its own line.
Change panic() to always print a newline itself, and update callers not to.
In addition, panic() was occasionally called with a leading newline, and
occaionally with trailing punctuation which seems rather redundant given the
surrounding context. Fix up these sitiuations as well.

This has been compile tested on arm32 and arm64.
George:
I request that this is included for 4.4 - It is just formatting changes rather
than functional ones
