ish: use magic number to verify persistent data
Move persistent data definitions to a structure and have linker script
define the address of the symbol into the AON ROM (persistent data
storage). Use the magic number "ISHd" to verify persistent data
storage and copy to static memory when valid. Commit changes from the
local copy during reset.
BUG=b:133779707,b:133647823,b:132059981
BRANCH=none
TEST=power-on is only reset flag under cold reset, panic data
persists, watchdog reset produces correct reset flags, UART always
printing system info on boot
