It was noticed that Clearfog is currently broken with this newly
introduced early_init_done() function. Apparently the timer is enabled
here when U-Boot is run but not configured - at least not correctly.
Resulting in a hangup in the timer reading functions.
To fix this, also read the value of the reload register and check it's
value with the one written to by U-Boot. Only if this matches, the
init has already been done.

We've noticed that at least one Kirkwood board (Pogo v4) has problems
with the new orion DM timer implementation. Debugging revealed that this
issue is related with the static variable "early_init_done" which does
not work correctly before relocation in all cases.
This patch removes this static variable and replaces it's functionality
via a function that detects if the timer is already initialized.

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.

Move the code making sure that the timer is initialized only once into
orion_timer_init(), which is called from timer_early_init() and from
orion_timer_probe(). This way the timer is not re-initialized.

Add timer_get_boot_us() to support boards, that have CONFIG_BOOTSTAGE
enabled, like pogo_v4.

This patch adds support for other Marvell Armada SoC's, supporting the
25MHz fixed clock operation, like the Armada XP etc.

While testing on some Kirkwood platforms it was noticed that the timer
did not function correctly all the time. The driver did not correctly
handle 32bit timer value wrap arounds. Using the timer_conv_64()
conversion function fixes this issue.
