DA9053 chip submission was done by Linaro and now they have agreed that
we will be only responsible for DA9053 submission too so now we can
skip the posted DA9053 patch.

Regarding file naming convention da9052 seems to be appropriate since 
DA9053 chip is update of DA9052 and also DA9052 is the umbrella name
for the whole family.
