ARM: imx6sx: use correct clocks for GPT ...

This is a stop gap solution until the upstream DT is fixed. In Linux this isn't
an issue as the driver prefers the "osc_per" clock, falling back to "per" and
then doing different things based on the SoC type and if the input clock rate
matches 3MHz. As this isn't really how the hardware works, but a fragile mix of
the clock driver exposing a clock with a faked frequency and system knowledge in
the GPT driver I prefer not to replicate this horrors in the Barebox driver,
but instead just use the system clock source.

i.MX: ocotp: Change MAC address layout for VFxxx ...

For reasons unclear VFxxx port of U-Boot chose to store MAC address in
OCOTP using a layout that is incompatible with rest of i.MX
world (both in U-Boot and Barebox). Unfortunately for us, that means
that there are a number of boards out there that have had their MAC
addresses programmed using U-Boot and in order to properly support
those boards we need to change VFxxx port of Barebox to be compatible.

Since the number of Barebox users on VFxx is in single digits, just
chage the layout to that of U-Boot without trying to make this a
configurable option.

dove: move memory controller remapping before RAM detection ...

Compared to other mvebu cpus the memory controller registers are in
their own register window that can be moved independently of the mbus
register window.

Since commit f05c6e095cf8 the available RAM configured by the boot ROM
is read out earlier. This happens to be before the memory controller
register window is moved and so dove_memory_find() fails. To fix this
move the memory controller window together with the mbus window.

This change allows to boot barebox first stage again on a Solidrun
Cubox.
