The "i2cbcdev" sneaked in when implementing this function for the
bootcounter use case. Obviously the intention was to use prop_name
instead.

This new function enhances the i2c_get_chip*() toolbox by implementing a
variant that does not require a chip_addr. Instead, the desired device
is pointed to by a phandle.

In SPL probing of the designware_i2c device on the StarFive VisionFive 2
board fails with

    dw_i2c: mode 0, ic_clk 1000000, speed 100000,
    period 10 rise 1 fall 1 tlow 5 thigh 4 spk 0
    dw_i2c: bad counts. hcnt = -4 lcnt = 4
    device_probe: i2c@12050000 failed to probe -22

When changing the offset for the high phase from 7 to 3 the device is
probed correctly. This now matches the value from the Linux driver.

Without this fix the memory size of the StarFive VisionFive 2 board cannot
be read from EEPROM.

Allwinner seems to typically stick to a common MMIO memory map for
several SoCs, but from time to time does some breaking changes, which
also introduce new generations of some peripherals. The last time this
happened with the H6, which apart from re-organising the base addresses
also changed the clock controller significantly. We added a
CONFIG_SUN50I_GEN_H6 symbol back then to mark SoCs sharing those traits.

Now the Allwinner D1 changes the memory map again, and also extends the
pincontroller, among other peripherals.
To mark this generation of SoCs, add a CONFIG_SUNXI_GEN_NCAT2 symbol,
this name is reportedly used in the Allwinner BSP code, and prevents us
from inventing our own name.

Add this new symbol to some guards that were already checking for the H6
generation, since many features are shared between the two (like the
renovated clock controller).

This paves the way to introduce a first user of this generation.

U-Boot's generic GPIO_EXTRA_HEADER is a convenience symbol to allow code
to more easily include platform specific GPIO headers. This should not
be needed in a DM world anymore, since the generic GPIO framework
handles that nicely.
For Allwinner boards we still need to deal with non-DM GPIO in the SPL,
but this should become the exception, not the rule.

Make this more obvious by removing the definition of GPIO_EXTRA_HEADER,
and just force every legacy user of platform specific GPIO to include
the new sunxi_gpio.h header explicitly. Everyone doing so should feel
ashamed and should find a way to avoid it from now on.

Sandbox unit tests in U-Boot proper load a test device tree to have some
devices to work with. In order to do the same in SPL, we must enable
SPL_OF_REAL. However, we already have SPL_OF_PLATDATA enabled. When
generating platdata from a devicetree, it is expected that we will not need
devicetree access functions (even though SPL_OF_CONTROL is enabled). This
expectation does not hold for sandbox, so allow user control of
SPL_OF_REAL.

There are several places in the tree where conditions involving OF_PLATDATA
or OF_REAL no longer function correctly when both of these options can be
selected at the same time. Adjust these conditions accordingly.
