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.

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.
