[PATCH net-next v2 2/3] net: phy: microchip_t1: Enable pin out specific to lan887x phy for PEROUT signal

[Divya Koppera <divya.koppera@microchip.com>]

Adds support for enabling pin out that is required
to generate periodic output signal on lan887x phy.

Signed-off-by: Divya Koppera <divya.koppera@microchip.com>
