V831 SoC is one of sun8i family (with Cortex-A7 CPUs), and it follows a
similar memory map with H6.
Add support for it. The detection for H6-style memory map is positive on
V831, because it have the same version of GIC at the same address.

Allwinner H6 SoC has a totally different memory map and different clock
control unit with other SoCs.
Add support for it in uart0-helloworld-sdboot.
To avoid writing blindly into the device MMIO area first (for triggering
the SRAM version register), we query the known content of some GIC register
to verify we are looking at an H6 memory map.

Allwinner A80 and H6 SoC has totally different memory map with other
Allwinner SoCs, and so the GPIO/UART0 base addresses are different on
these SoCs.
Use a static variable to store the base address, to fit these SoCs with
different memory map.

With fixed SID reading routine, it's now possible to differ H2+ with H3
with SID.
Tested on an Orange Pi One and an Orange Pi Zero.

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.
