This commit adds 'uclass_platdata' field to 'struct udevice', which
can be automatically allocated at bind. The allocation size is defined
in 'struct uclass_driver' as 'per_device_platdata_auto_alloc_size'.
New device's flag is added: DM_FLAG_ALLOC_UCLASS_PDATA, which is used
for memory freeing at device unbind method.
As for other udevice's fields, a complementary function is added:
- dev_get_uclass_platdata()

This commit extends the uclass-internal functions by:
- uclass_find_first_device()
- uclass_find_next_device()
For both functions, the returned device is not probed.
After some cleanup, the above functions are called by:
- uclass_first_device()
- uclass_next_device()
for which, the returned device is probed.

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.
Tested on the Integrator/AP hardware.

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.

According to the MPC8555/MPC8541 reference manual the SS_EN (source
synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set
during initialization.
>From section 9.4.1.8 of that manual:
Source synchronous enable. This bit field must be set during
initialization. See Section 9.6.1, "DDR SDRAM Initialization
Sequence," details.
0 - Reserved
1 - The address and command are sent to the DDR SDRAMs source
synchronously.
In addition, Freescale application note AN2805 is also very clear that
this bit must be set.
This patch reverts a change introduced by commit
457caecdbc.
Testing Done:
Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS
and inspected the generated assembly code to verify the SS_EN bit was being
set. There is one extra instruction emitted:
fff9b774: 65 29 80 00 oris r9,r9,32768
Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no
additional instructions were emitted related to this patch.

Adjust the error handling to use errno.h instead of returning -1. Change
leaf functions to pass in the arguments they require rather than struct
eth_device. Apart from simplifying the code it makes is easier to reuse
these functions for driver model, since mostly they actually only use
struct dw_eth_priv (which we can keep).
Create a stub for each Ethernet operation function. This will allow use to
share code with the driver model versions.

When driver model is used for Ethernet a few functions are passed a udevice
instead of an eth_device. Also add a function to find a PHY type given its

CONFIG_SPI does not exist in Kconfig in the first place, so the
dependency "depends on DM && SPI" is never met, i.e., DM_SPI_FLASH
can never be enabled (unless you ignore the dependency in an illegal
way. See below.)
Actually, some defconfigs such as socfpga_*_defconfig define
CONFIG_DM_SPI_FLASH=y, but it never appears in the .config file
because of this wrong dependency.
On the other hand, all the Tegra boards enable DM_SPI_FLASH because
config DM_SPI_FLASH
default y
silently ignores the dependency.
Unfortunately, this style of CONFIG definition is abused everywhere
in U-Boot, so we easily miss such a wrong dependency.
