John Vincent 77940d8531 drivers: soc: cal-if: Prevent optimization of structs on fvmap_copy_from_sram 
Newer versions of Clang tend to apply heavier optimizations than GCC, especially if -mcpu is set. Because we are applying optimizations to the LITTLE core (see b92e1e70898f515646142736df8d72c43e97e251) kernel panics during boot, citing inability to access memory regions on fvmap_init.

Since we need these optimizations for performance reasons, the only way to resolve this is to solve the issue. Samsung already did something similar to cal-if before.

We only needed to make fvmap_header/header volatile and has been tested to work.
