[PATCH net-next v2 02/10] net: dsa: microchip: add the number of periodic signals to chip infos

["Bastien Curutchet (Schneider Electric)" <bastien.curutchet@bootlin.com>]

The number of periodic signals available is hardcoded to 3 while
KSZ8463 can produce 12 different periodic signals.

Add an n_per_out attribute to the struct ksz_chip_data to make this
setting configurable.
Set it to 3 for all the PTP-capable switches.
