Convince compilers to put constant data into the .rodata section
This patch reduces the stack usage by declaring 'const' stack variables as 'static const' so they end up in the .rodata section instead of being copied from there to the stack for every invocation of the corresponding function. As a plus we end up in having a smaller binary as the "copy from .rodata to stack" code isn't emitted by the compiler any more (roughly -100 bytes). Corresponding to flashrom svn r1252.
