net: ethernet: stmmac: dwmac-rk: rework optional clock handling

Browse source

The clock requesting code is quite repetitive. Fix this by requesting
the clocks via devm_clk_bulk_get_optional. The optional variant has been
used, since this is effectively what the old code did. The exact clocks
required depend on the platform and configuration. As a side effect
this change adds correct -EPROBE_DEFER handling.
