mlxsw: spectrum_ptp: Fix compilation warnings

Browse Source 
In case that 'CONFIG_PTP_1588_CLOCK' is not enabled in the config file,
there are implementations for the functions
mlxsw_{sp,sp2}_ptp_txhdr_construct() as part of 'spectrum_ptp.h'. In this
case, they should be defined as 'static' as they are not supposed to be
used out of this file. Make the functions 'static', otherwise the following
warnings are returned:

"warning: no previous prototype for 'mlxsw_sp_ptp_txhdr_construct'"
"warning: no previous prototype for 'mlxsw_sp2_ptp_txhdr_construct'"

In addition, make the functions 'inline' for case that 'spectrum_ptp.h'
will be included anywhere else and the functions would probably not be
used, so compilation warnings about unused static will be returned.

Fixes: 24157bc69f45 ("mlxsw: Send PTP packets as data packets to overcome a limitation")
