Since a device can have children in the same uclass as itself, we need
to handle unbinding carefully: we must allow that unbinding a device in a

commit aed2fbef5e
"dm: serial: Tidy up the pl01x driver"
caused a regression on (real hardware) PL010 by omitting
to update the line control register when switching baudrate.
Fix this by inlining the missing write to the baud control
register.
Also renaming the set_line_control() function to
pl011_set_line_control() since this function is clearly
PL011-specific, and it won't suffice to call that to
set up line control.

When accessing PHY registers it is often desirable to only update
selected bits, so it is necessary to first read the current value
before writing back an modified value with the relevant bits
updated.
To simplify this and to allow such operations to be incorporated
into simple shell scripts propose adding a 'modify' option to the
existing mii command, which takes a mask indicating the bits to
be updated in addition to a data value containing the new bits,
ie, <updated> = (<data> & <mask>) | (<current> & ~<mask>).

Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have
interrupts enabled by default. If the interrupt is not treated later by
the OS and the PHY's interrupt line is enabled and shared with other
interrupts, the system will get an interrupt storm. This patch disables
the interrupt for PHY devices that use one of the current Realtek
Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L)
have the interrupt masked. In this case, the functionality of the PHY
should not be afected since this patch brings INER and INSR registers to
their default values.

U-Boot on this board grew a long time ago past the 384 KiB that
it reserves for the U-Boot image, before the environment. Thus,
saveenv overwrites the U-Boot image and bricks the board.
I tried to find out when U-Boot grew beyond this point, but there is a
long stretch in the history where this board did not build -- and
AFAICT when it did fit in 384 KiB, it was missing vital features such
as fdt support. Turning off CONFIG_VIDEO was not enough to make it
fit. Thus, I don't think we have any choice other than to move the
environment.

U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code. It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.
The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).
Also remove a few other small unused functions.

Booke does not require exception vectors to be located at address zero.
U-Boot was doing so anyway, simply because that's how it had been done
on other PPC. The downside of this is that once the OS is loaded to
address zero, the exception vectors have been overwritten -- which
makes it difficult to diagnose a crash that happens after that point.
The IVOR setup and trap entry code is simplified somewhat as a result.
Also, there is no longer a need to align individual exceptions on 0x100
byte boundaries.
