a) you need the timer even before talking to anything - u-boot needs it
for basic delay - so add the pre-ram property.
b) what you are doing in u-boot currently a hack - am625 in u-boot got
it fixed the right way - follow the model then you dont need the hackery
with deleting clock and power-domains properties.
