The watchdog register isn't in the same place, nor uses the same values
to trigger a reset.

Allwinner H6 is a new SoC with its memory map changed.

Add its SoC info, including SRAM addresses and SID address.

Use a hardwired L.NOP instruction from the OpenRISC reset
vector as a way to check if the workaround is necessary.
Because these L.NOP instructions are guaranteed to be there
and are read-only, this is the most reliable non-invasive test.

Reading SID would be less reliable because it is one-time
programmable and theoretically may be set to zero on some boards.

H3 SID controller has some bug, that makes the initial value at
0x01c14200 wrong.

This commit workarounds this bug by reading them with register access
first.

This is a preparatory step. Instead of using memory-based access,
we might want to retrieve SID keys (e-fuses) via SID registers.
For this, it's convenient if the plain base address is available.

The V3s SoC looks like A10/13/20 in SRAM mapping and SID address.

Add support for it.

open_fel_device() will automatically provide this member field,
based on the SoC ID from FEL/BROM version data. The field will
either receive a human-readable identifier, or the ID in 4-digit
hexadecimal representation (for unknown SoCs).

The SID block in the A80 is at 0x01c0e000, with the e-fuses we care
about at offset 0x200 within the block.

The R40 is marketed as the successor to the A20. The SRAM layout is the
same as the A20, but there doesn't seem to be a secure SRAM block.

The SID block is at a completely different address. The layout is the
same as the newer SoCs, with the e-fuses at an offset of 0x200.

Besides having fewer lines of code, the #define macros should
also prevent users from accidentally using these names without
braces (i.e. as function pointers). Instead, this will cause
compiler errors now.

soc_info.c: add "A10s" label in comment for SoC ID 0x1625.

While at it, modify the former "sram_info" identifiers
to carry a broader "soc_info" meaning.
