("ARM: mvebu: Enable PUP register")
correctly enables devices that are disabled after boot-up due to
some Design For Testability registers.
However, although harmless on Armada 370, call the code conditionally
on Armada XP only. While at it, move PUP register defines to SYSCTL
registers where they belong to.

Registering mbus driver as platform driver is a little late for

i2c: mv64xxx: continue probe when clock-frequency is missing
The "clock-frequency" DT property is listed as optional, However,
the current code stores the return value of of_property_read_u32 in
the return code of mv64xxx_of_config, but then forgets to clear it
after setting the default value of "clock-frequency". It is then
passed out to the main probe function, resulting in a probe failure
when "clock-frequency" is missing.

GPIO LEDs can suffer from deferred probing due to failing gpio request.
Instead of registering each gpio led independently, pre-allocate an
array of struct gpio_led for all and tear it down properly if probing
of one leds fails. While at it, silence error messages on -EPROBE_DEFER.
