Nicolas Pitre 8ea0de4b88 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.

This patch modifies the number of total GPIO lines for Bank F
for Samsung S5P6440 and S5P6450 SoCs from 2 to 16.
This is necessary as the GPIO lines from 0 to 13 are reserved
and only lines 14 and 15 are used. As during initialization,
the line number starts at 0, putting 2 does not solve the
intended purpose.
