ARM: make timer variables in gt_t available for all ARM platforms
All code that attemots to access variables in BSS before relocation
(for example directly or indirectly by board_init_f()) needs to be
fixed. Especially timer.c needs to fix on most of the ARM platforms.
This patch makes timer related variables in gd_t available for
all ARM implementations.

I doubt the stack_setup() was defective before:
we load the current location of _start and compare against destination
of relocate_code(). If we are already there we shoud skip the
relocation and jump over to clear_bss. Before the clear_bss was also skipped.

hwconfig: Fix dummy initialization of {board, cpu}_hwconfig
Since board_hwconfig & cpu_hwconfig are defined as weak and dont have a
default value they will get put into the BSS if they aren't defined
elsewhere. This is problematic as we try to utilize hwconfig before
we've relocated and thus BSS isn't setup.
Instead of giving dummy values in the board files that utilize this
feature, we can just initialize the variables to an empty string and
thus move them out of the BSS if they aren't defined elsewhere.
Also made board_hwconfig & cpu_hwconfig arrays to reduce size associated
with string pointers vs arrays.

Some systems need to relocate the env_addr pointer early because the
location it points to will get invalidated before env_relocate is
called. One example is on systems that might use a L2 or L3 cache
in SRAM mode and initialize that cache from SRAM mode back to being
a cache in cpu_init_r.
We set this on the 85xx boards that have support for NAND, SPI, or
SDHC/MMC boot support as they use a secondary cache in SRAM mode and
need the env_addr pointer relocated since we change from SRAM to normal
cache mode in cpu_init_r.
Also removed CONFIG_SYS_SPL as its not used anywhere.

cfi_flash: fix bug introduced while recent change to flash_get_size()
commit ec50a8e389863ac35bfd9d9a2e8b30187318e59e
"cfi_flash: handle 'chip size exceeds address window' situation"
added 3rd argument to flash_get_size() but didn't fix all the
function calls from the board specific code. Many boards have
their own flash_get_size() definitions in the board code and
use them there, but some boards (e.g. tqm834x, tqm85xx, pdm360ng)
use flash_get_size() from the cfi_flash.c driver.
The bug shows up if the value of the "max_size" argument (which
is not defined when calling the function with two arguments)
happens to be less than "info->size". In this case on the
affected boards we end up with a bank of reduced size and
in the worst case might even be not able to update U-Boot or
to boot the kernel from flash:

POWERPC: enable --gc-sections and -ffunction-sections -fdata-sections
The switch from archive libraries to partial linking has introduced a
number of problems, that are non-trivial to solve. For example, it is
no longer possible to include individual object files in the linker
script as we did before for example in the case of boards with
embedded environment to fill up the gap caused by the need to align
the environment on flash erase block boundaries.
The best (but unfortunately not easiest) approach to address this
problem is to enable -ffunction-sections (and -fdata-sections) so
we can again (and even in much finer granularity) place certain code
where we want it. When doing this step, it seems only consequent to
also add --gc-sections which has the added benefit of reducing the
memory footprint of the U-Boot image (both in flash and in RAM).
Unfortunately, this requires changes to a lot of linker scripts.
