The SPL for socfpga gen5 currently takes all peripherals out of reset

some device tree nodes are missing reset handles.
Since the socfpga gen5 devicetrees are currently in sync with Linux 4.20,
and these reset handles are not added to Linux, yet, let's add them to
U-Boot specific dtsi files to ease future merging.
This adds a new file socfpga_u-boot.dtsi (note the '_' - if using a '-'
this file gets pulled in for some a10/s10 devicetrees) that adds the
missing reset handles.

Shouldn't all this be in u-boot specific DTs, instead of the ones
imported from Linux ?
The "u-boot,dm-pre-reloc" thing should of course stay in u-boot specific
DTs. But I had to add many missing "resets = " references that are yet
missing in upstream Linux DTs. Dinh is in the process of adding them and
I'll make sure to sync that back to U-Boot once it's in Linux mainline
git. I just did not want to wait until that happens...

Simon
