When the CONFIG_HAVE_CLK is selected for the system, the stmmac_pci_probe
will fail with dmesg:
[ 2.167225] stmmaceth 0000:00:14.6: enabling device (0000 -> 0002)
[ 2.178267] stmmaceth 0000:00:14.6: enabling bus mastering
[ 2.178436] stmmaceth 0000:00:14.6: irq 24 for MSI/MSI-X
[ 2.178703] stmmaceth 0000:00:14.6: stmmac_dvr_probe: warning: cannot
get CSR clock
[ 2.186503] stmmac_pci_probe: main driver probe failed
[ 2.194003] stmmaceth 0000:00:14.6: disabling bus mastering
[ 2.196473] stmmaceth: probe of 0000:00:14.6 failed with error -2
This patch fix the issue by breaking the dependency to devm_clk_get()
as the CSR clock can be obtained at priv->plat->clk_csr from pci driver.
