ARM: Add relocatable binary support ...

For making the same binary executable on different SoCs which have
different DRAM addresses we have to be independent of the compile
time link address.

This patch adds relocatable binary support for the ARM architecture.
With this two new functions are available. relocate_to_current_adr
will fixup the binary to continue executing from the current position.
relocate_to_adr will copy the binary to a given address, fixup the
binary and continue executing from there.

For the PBL and the real image relocatable support can be enabled
independently. This is done to (hopefully) better cope with setups
where the PBL runs from SRAM or ROM and the real binary does not.

ARN: fixup vector addresses for relocatable binaries ...

With relocatable binaries the vector addresses cannot be supplied by
the linker. This adds support for fixing them up during runtime.

ARM: provide accessor functions for linker variables ...

With relocatable binaries the linker is not able to supply absolute
addresses. These only get available when the relocation function is
being run. Since for early initialization we need some variables
before relocation, we supply them relatively to some known address
in the binary. This means that the variables have to be converted
to absolute addresses during runtime.

This patch adds a C macro and an assembly macro to calculate the
variables during runtime.

ARM: add early mmu cache flush function and use it in setup_c ...

Since recently with MMU_EARLY support it may happen that setup_c
runs with data caches enabled, so we have to make sure the caches
are flushed before we jump to the new binary.

ARM: make cpu architecture detection available as static inline function ...

When we have multi cpu support compiled in we need the cpu architecture
early so that we can pick the correct cacheflush function. Make it available
as static inline function and add a comment above it that this function
normally should not be used.

mtd: always write page when oob is given ...

Since recently we check for the page being written for not being
empty and do not actually write it when it is. This fails for a
freshly created flash bad block table when all blocks are good.
In this case the bbt code will try to write an empty page, but
with the BBT marker in OOB. This page never gets written, so the
BBT code will not find a bad block table during next start up and
writes it again. Fix this by checking if we want to write OOB data,
if we do, then write the page, even if the data is empty.
