ARM: zImage: remove the static qualifier from global data variables
To be able to relocate the .bss section at run time independently from the rest of the code, we must make sure that no GOTOFF relocations are used with .bss symbols. This usually means that no global variables can be marked static unless they're also const. Let's remove the static qualifier from current offenders, or turn them into const variables when possible. Next commit will ensure the build fails if one of those is reintroduced due to otherwise enforced coding standards for the kernel.
