Reset and initialize the PHY once in the probe() function rather than
doing it over and over again is start() function. This requires us to
keep the clock enabled while the driver is in use. This significantly
reduces the time between transfers as the PHY doesn't have to restart
autonegotiation between transfers, which takes forever.

I've noticed that the first ethernet packet after PHY link establishment
is not tranferred correctly most of the time on my AT91SAM9G25 board.
Here I usually see a timeout of a few seconds, which is quite
annoying.
Adding a small delay (10ms in this case) after the link establishment
helps to solve this problem. With this patch applied, this timeout
on the first packet is not seen any more.

some dpmacs in armv8a based freescale layerscape SOCs can be
configured via both serdes(sgmii, xfi, xlaui etc) bits and via
EC*_PMUX(rgmii) bits in RCW.
e.g. dpmac 17 and 18 in LX2160A can be configured as SGMII from
serdes bits and as RGMII via EC1_PMUX/EC2_PMUX bits
Now if a dpmac is enabled by serdes bits then it takes precedence
over EC*_PMUX bits. i.e. in LX2160A if we select serdes protocol
that configures dpmac17 as SGMII and set the EC1_PMUX as RGMII,
then the dpmac is SGMII and not RGMII.
Therefore, in fsl_rgmii_init function of SOC, we will check if the
dpmac is enabled or not? if it is (fsl_serdes_init has already enabled
the dpmac), then don't enable it.

This driver was written for Arria10, but it applies to Gen5, too.
The main difference is that Gen5 has 2 MACs (Arria10 has 3) and the
syscon bits are encoded in the same register, thus an offset is needed.
This offset is already read from the devicetree, but for Arria10 it is
always 0, which is probably why it has been ignored. By using this
offset when writing the phy mode into the syscon regiter, we can use
this driver to set the phy mode for both of the MACs on Gen5.
Since the PHY mode bits in sysmgr are the same even for Stratix10,
let's drop the detection of the sub-mach by checking compatible
version and just use the same code for all FPGAs.
To work correctly, this driver depends on SYSCON and REGMAP, so select
those via Kconfig when it is enabeld.
Tested on socfpga_socrates (where the 2nd MAC is connected, so a shift
offset is required).

For KSZ9021, all skew register fields are 4-bit wide.
For KSZ9031, the clock skew register fields are 5-bit wide.
The common code in ksz90x1_of_config_group calculating the combined
register value checks if the requested value is above the maximum
and uses this maximum if so. The calculation of this maximum uses
the register width, but the check itself does not. It uses a hardcoded
value of 0xf, which is too low in case of the 5-bit clock (0x1f).
This detail was probably lost during driver unification.
Effect (only for KSZ9031 clock skews): For values greater 900 (== 0ps),
this silently results in 1860 (== +960ps) instead of the requested one.
Fix the check by using the bit width instead of hardcoded value(s).

The designware driver has a bug in setting the tx length into the dma
descriptor: it always or's the length into the descriptor without
zeroing out the length mask before.
This results in occasional packets being transmitted with a length
greater than they should be (trailer). Due to the nature of Ethernet
allowing such a trailer, most packets seem to be parsed fine by remote
hosts, which is probably why this hasn't been noticed.
Fix this by correctly clearing the size mask before setting the new
length.
