NET: designware: fix clock enable
After commit ba1f966725223 ("net: designware: add clock support")
we got NET broken on axs101 and axs103 platforms.
Some clock don't support gating so their clock drivers don't
implement .enable/.disable callbacks. In such case clk_enable
returns -ENOSYS.
Also some clock drivers implement .enable/.disable callbacks not for all
clock IDs and return -ENOSYS (or -ENOTSUPP) for others.
If we have such clock in 'clocks' list of designware ethernet controller
node we fail to probe designware ethernet.
Fix it.
