At present the debug UART is only set up in SPL, on the assumption that
the boot flow will always pass through there. When booting from coreboot,
SPL is not used, so the debug UART is not available.
Move the code into a common place so that it can be used in U-Boot proper
also. Add the required init to start_from_spl.S as well.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

At present this driver calls malloc() to start a new platform data
structure, fills it in and tells driver model to use it.
We want to avoid malloc, particularly with the new version of of-platdata.
Create a new struct which encompasses both the dtd struct and the ns16550
one, to avoid this. Unfortunately we must copy the data into the right
place for the ns16550 driver. Add some comments about this.

With the new of-platdata, these need to be available to dt_platdata.c
so must be in header files. Move them.

When comparing hex dumps it is useful to see the offsets of the registers.
Add them in where they correspond to a multiple of 16.
Possibly it would be useful to have a a command to output the FSP values
in human-readable form, making use of the fsp_bindings implementation.
