timekeeping: Address parameter documentation issues for various functions

The kernel-doc parser complains:

kernel/time/timekeeping.c:1543: warning: Function parameter or member
'ts' not described in 'read_persistent_clock64'

kernel/time/timekeeping.c:764: warning: Function parameter or member
'tk' not described in 'timekeeping_forward_now'

kernel/time/timekeeping.c:1331: warning: Function parameter or member
'ts' not described in 'timekeeping_inject_offset'

kernel/time/timekeeping.c:1331: warning: Excess function parameter 'tv'
description in 'timekeeping_inject_offset'

Add the missing parameter documentations and rename the 'tv' parameter of
timekeeping_inject_offset() to 'ts' so it matches the implemention.

Sentence after the colon starts with an uppercase letter.
s/explaination/explanation/ Please use a spell checker.

Also what is ts/tk? The short log sentence has to be concise and easy to
understand and decribe what the patch does.

'This patch fixed' ?

First of all, sentences start with an uppercase letter, but also please
do:

# git grep 'This patch' Documentation/process/

and read the paragraph which matches.

This is _not_ adding documention, it's fixing the wrongly named
parameter.

Thanks,
