The serial_register function never fails (always return 0), so change it
to a void function to avoid wasting overhead on it.

Rather than sticking arch/board/driver specific logic in the common
serial code, push it all out to the respective drivers.  The serial
drivers declare these funcs weak so that boards can still override
things with their own definition.

Some toolchains enable security warning flags by default, but these don't
really make sense in the u-boot world.  Such as forcing changes like:
	-printf(foo);
	+printf("%s", foo);

So disable the flags when the compiler supports them.  Linux has already
merged a similar change in their build system.

Newer SST flashes have dropped the Auto Address Increment (AAI) word
programming (WP) modes in favor of the standard page programming mode
that most flashes now support.  So add a flags field to the different
flashes to support both modes with new and old styles.

In some circumstances, reset_timer_masked() was called be timer_init() in
order to perform architecture specific timer initialisation. In such
cases, the required code in reset_timer_masked() has been moved into
timer_init()

There is no need to use set_timer(). Replace with appropriate use of
get_timer()

When booting with a ramdisk we bump the amount of memory reserved for
the device tree by FDT_RAMDISK_OVERHEAD.  However we did not increase
the actual size in the device tree blob to match.

Its possible on boundary cases that we dont have enough memory according
to the device tree blob and get errors like:

WARNING: could not set linux,initrd-end FDT_ERR_NOSPACE

We can easily fix this by setting the device tree size at the same time
we bump the amount of memory reserved for the device tree.
