lib/hardwaremain.c: Hide preprocessor guards in header
The `location` member of `struct boot_state_callback` is conditionally
guarded depending on `CONFIG(DEBUG_BOOT_STATE)` using preprocessor. It
is probably intended to save some space when the `location` strings do
not get printed. However, directly using the `location` member without
any guards will cause a compile-time error. Plus, preprocessor-guarded
code gets nasty really quickly.
In order to minimise preprocessor usage, introduce the `bscb_location`
inline helper function, which transforms the compile-time error into a
link-time error. It is then possible to substitute preprocessor guards
with an ordinary C `if` statement.
