dm: core: Fix allocation of empty of-platdata
With of-platdata we always have a dtv struct that holds the platform data
provided by the driver_info record. However, this struct can be empty if
there are no actual devicetree properties provided.
The upshot of empty platform data is that it will end up as a zero-size
member in the BSS section, which is fine. But if the driver specifies
plat_auto then it expects the correct amount of space to be allocated.
At present this does not happen, since device_bind() assumes that the
platform-data size will always be >0. As a result we end up not
allocating the space and just use the BSS region, overwriting whatever
other contents are present.
Fix this by removing the condition that platform data be non-empty, always
allocating space if requested.
This fixes a strange bug that has been lurking since of-platdata was
implemented. It has likely never been noticed since devices normally have
at least some devicetree properties, BSS is seldom used on SPL, the dtv
structs are normally at the end of bss and the overwriting only happens
if a driver changes its platform data.
It was discovered using sandbox_spl, which exercises more features than
a normal board might, and the critical global_data variable 'gd' happened
to be at the end of BSS.

reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.
This transformation was done with the following coccinelle patch:

expression argvalue;

- reset_cpu(argvalue)

board: ns3: Remove superfluous reset logic
The current implementation of reset_cpu() in the ns3 board code does not
archieve what it is supposed to (according to the comments), due to
a number of reasons:
1. The argument to reset_cpu() is _not_ actually passed from the
`reset` command, but is set to 0 in all call-sites (in this
specific case, see arch/arm/lib/reset.c). Thus, performing
different kinds of resets based on its value will not work as
expected.
2. Contrary to its documentation, the passed argument is not
interpreted, but a static `L3_RESET` define is used. The other
comment properly notes that this will always perform a L3 reset,
though.
3. The "parsing" of the static `L3_RESET` value is not even using the
upper and lower nibble as stated in the comment, but uses the last
two decimal digits of the value.
This is currently one of the only implementations left in U-Boot, which
make "use" of the value passed to reset_cpu(). As this is done under
false assumption (the value does not have any meaning anymore), it makes
sense to bring it into line with the rest and start ignoring the
parameter.
This is a preparation for removal of the reset_cpu() parameter across
the entire tree in a later patch.
