This splits out a per-SoC IRQ range handling, so that the
DB8500 and DB5500 SoC:s can reuse aproximately the same IRQ
range with the largest span setting the roof. The same change
is done for the boards, mutatis mutandis, with a new file for
the U5500 board.

Commit e2a083dc0da9aa6437e14811198379b18cdfa7f8
"ARM: consolidate SMP cross call implementation" broke the ux500
compilation since the smp.h header declared a function called
from headsmp.S. This fixes it up by declaring it locally instead.

Rather than having each platform class provide a mach/smp.h header for
smp_cross_call(), arrange for them to register the function with the
core ARM SMP code instead.

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.

The current code support of dummy timers in absence of local

so that on few SOC version if the local timers aren't supported
kernel can switch to dummy timers. OMAP4430 ES1.0 does suffer from
this limitation.
