arm: Switch to -mno-unaligned-access when supported by the compiler
When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level. We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.
To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
tag of the kernel.

omap4_common: config: remove I2C for SPL mode
Commit 6789e84ecaa8f45d053084e08c381284a04abff7 (i2c, omap24xx:
convert driver to new mutlibus/mutliadapter framework) intended to
make I2C driver compatible with latest changes. It unfortunately has
had a impact on size on SPL as well. For example on SDP4430,
32032 bytes before/MLO
35416 bytes after/MLO
With this mentioned commit, MLO stops booting on SDP4430 as only 32K
is accessible for non-secure (bootloader) s/w on GP devices and the size
increase to 56K fails boot.
On the latest u-boot commit e7be18225fbea76d1f0034b224f0d1e60f07cfcf,
MLO is now at size 35592 bytes, However, I2C is not necessary for SPL
to function as we use SR_I2C for controlling the PMIC.
Disabling I2C reduces MLO to 32224 bytes which allows
OMAP4 GP platform to boot up.
Since this is common for all OMAP4 platforms, remove the need for I2C
for SPL builds in the common config.

This commit changes the working directory

Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
