bit PCIE_PHYMISC_FORCE_RCV_DET is only for l1c&l2c to fix WoL issue,
other chips set bit5 of REG_MASTER_CTRL --- this way could save more
power than the former, and the bit should be kept all time.
l2cb 1.x has special setting for L0S/L1
l2cb 1.x & l1d 1.x should clear Vendor Message on some platforms,
otherwise it will cause the root complex hang.

some platforms(BIOS or OS) may change ASPM configuration in
PCI Express Link Control Register directly and dynamically
regardless the device driver installation.
Checking if ASPM support during the driver init phase by reading
PCI Express Link Contrl Register doesn't make sense.
This refine/update assume L0S/L1 is defalut enabled as hw->ctrl_flags

On some platforms, for example where we are doing the bring-up,
the csr clock is not passed from the framework and the Ethernet
device driver is failing when it can work w/o any issues and
using the default values. So this patch just warnings the case
of the csr clock cannot be acquired but w/o failing the probe
step. I have just tested it on ST STiH415 SoC (ARM).

Recently the dma parameters that can be passed from the platform
have been moved from the plat_stmmacenet_data to the stmmac_dma_cfg.

In case of this new structure is not well allocated the driver can
fails. This is an example how this field is managed in ST platforms

static struct stmmac_dma_cfg gmac_dma_setting = {
        .pbl = 32,
};

static struct plat_stmmacenet_data stih415_ethernet_platform_data[] = {
	{
		.dma_cfg = &gmac_dma_setting,
		.has_gmac = 1,
[snip]

This patch so verifies that the dma_cfg passed from the platform.
In case of it is NULL there is no reason that the driver has to fail
and some default values can be passed. These are ok for all the
Synopsys chips and could impact on performances, only.

Initialize slave device link state as down if ARP monitor is
active and net_carrier_ok() returns zero. Also shift initial
value of its last_arp_tx so that it doesn't immediately cause
fake detection of "up" state.

When ARP monitoring is used, initializing the slave device with
up link state can cause ARP monitor to detect link failure
before the device is really up (with igb driver, this can take
more than two seconds).
