net: dsa: microchip: Wrap timestamp reading in a function

Browse Source 
Timestamps are directly accessed through a register read in the
interrupt handler. KSZ8463's logic to access it will be a bit more
complex because the same interrupt can be triggered by two different
timestamps being ready.

Wrap the timestamp's reading in a dedicated function to ease the
KSZ8463's integration in upcoming patches.
