Add a b53_reg read/write command which allows inspecting the switch
registers. Because the Broadcom BCM53xx registers have different sizes,
we need to split the accesses in 8, 16, 32, 48 or 64 bits to obtain
expected results.

Add a minimalistic Broadcom BCM53xx (roboswitch) switch driver similar
to the Marvell MV88E617x. This takes care of configuring the minimum
amount out of the switch hardware such that each user visible port
(configurable) and the CPU port can forward packets between each other
while preserving isolation with other ports.
This is useful for e.g: the Lamobo R1 board featuring a Broadcom
BCM53125 switch.

This patch is ported from the Linux patch posted at [1] and applied to
net tree as commit f1e2400a80ff.
The purpose of this change is to fix the incorrect detection of the link
partner (LP) advertised capabilities which sometimes happens with this PHY
(roughly 1 time in a dozen)
This issue may cause the link to be negotiated at 10Mbps/Full or
10Mbps/Half when 100MBps/Full is actually possible. In some case, the link
is even completely broken and no communication is possible.
To detect the corruption, we must look for a magic undocumented bit in the
WOL bank (hint given by the SoC vendor kernel) but this is not enough to
cover all cases. We also have to look at the LPA ack. If the LP supports
Aneg but did not ack our base code when aneg is completed, we assume
something went wrong.
The detection of a corrupted LPA triggers a restart of the aneg process.
This solves the problem but may take up to 6 retries to complete.

The KS8721BL and KSZ9021 PHYs are software-incompatible, yet they
share the same ID. Drivers for bothe PHYs cannot safely coexist, so
the solution was to use #ifdefs to select between the two drivers.
As a result KSZ9031, which has a unique ID, is now caught in the
crossfire. Unless CONFIG_PHY_MICREL_KSZ9031 is defined, the KSZ9031
will not function properly, as some essential configuration code is
ifdef'd-out.
To prevent such situations, move the KSZ9000 drivers to a separate
file, and place them under a separate Kconfig option. While it is
possible to enable both KSZ8000 and KSZ9000 drivers at the same time,
the assumption is that it is highly unlikely for a system to contain
both a KSZ8000 and a KSZ9000 PHY, and that only one of the drivers
will be enabled at any given time.

This patch adds support for having a "fixed-link" to some other MAC
(like some embedded switch-device).
For this purpose we introduce a new phy-driver, called "Fixed PHY".
Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
described with a subnode below ethernet interface.
Most ethernet drivers (unfortunately not all are following same scheme
for searching/attaching phys) are calling "phy_connect(...)" for getting
a phy-device.
At this point we link in, we search here for a subnode called "fixed-
link", once found we start phy_device_create(...) with the special phy-
id PHY_FIXED_ID (0xa5a55a5a).
During init the "Fixed PHY" driver has registered with this id and now
gets probed, during probe we get all the details about fixed-link out of
dts, later on the phy reports this values.

Commit 525d187af ("net: phy: Optionally force master mode for RTL PHY")
added the define to force the PHY into master mode. Unfortunatly this is
an all or nothing switch. So it applies to either all PHY's or no PHY's.
The bug that define tried to solve was a buggy PLL in the RTL8211C only.
The Olimex OLinuXino Lime2 has gotten an upgrade where the PHY was
replaced with an RTL8211E. With this define however, both lime2 boards
are either forced to master mode or not. We could of course have a
binary for each board, but the following patch fixes this by adding a
'quirk' to the flags to the rtl8211b and rtl8211c only. It is now
possible to force master mode, but only have it apply to the rtl8211b
and rtl8211c.
