[PATCH] net: pcs: xpcs-plat: fix runtime PM initialization

[Coia Prant]

The driver calls `pm_runtime_set_active()` before runtime PM is enabled,
and before the clock is prepared and enabled.

This causes the clock to be unprepared/disabled later in the suspend
callback even though it was never prepared/enabled, resulting in warnings:

clk_csr already disabled
clk_csr already unprepared

Fix this by setting the initial runtime PM status to SUSPENDED instead
of ACTIVE.

The clock will be properly enabled when the device is first resumed
via runtime PM (e.g., during MDIO access).
