Default to bootm_size() when CONFIG_SYS_BOOTMAPSZ is not defined

This patch adds a function getenv_bootm_mapsize() for obtaining the
size of the early mapped region accessible by the kernel during early
boot. It defaults to CONFIG_SYS_BOOTMAPSZ, or if not defined,
defaults to getenv_bootm_size(), which in turn defaults to the size of
RAM.

getenv_bootm_mapsize() can also be overridden with a "bootm_mapsize"
environmental variable.

Stop passing around bootmem_base value.

For the calls to boot_relocate_fdt(), boot_get_cmdline(), and
boot_get_kbd(), the value of bootmem_base is always obtained by
calling getenv_bootm_low(). Since the value always comes from the
same source, the calling signature for those functions can be
simplified by making them call getenv_bootm_low() directly.

powerpc: Add cpu_secondary_init_r to allow for initialization post env setup

We can simplify some cpu/SoC level initialization by moving it to be
after the environment and non-volatile storage is setup as there might
be dependancies on such things in various boot configurations.

For example for FSL SoC's with QE if we boot from NAND we need it setup
to extra the ucode image to initialize the QE. If we always do this
after environment & non-volatile storage is working we can have the code
be the same regardless of NOR, NAND, SPI, MMC boot.

powerpc/85xx: Introduce CONFIG_SYS_EXTRA_ENV_RELOC

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.

WINBOND_83C553: enable only on boards that actually use it.

So far, only the BAB7xx board would call the initialise_w83c553f()
function for the WINBOND 83C553 chip, even though some other boards
(HIDDEN_DRAGON, Sandpoint8240, Sandpoint8245) enabled it in their
board configuration. These boards were also missing other config
settings needed for that, which resulted in build errors like this:

drivers/pci/libpci.o:(.got2+0x84): undefined reference to `ide_bus_offset'

Switch arch/powerpc/lib/board.c to call initialise_w83c553f() not on a
per-board base, but when a WINBOND_83C553 in enabled in a
configuration (like BAB7xx), and disable it in the boards that had
this set so far.

Switch from archive libraries to partial linking

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
