Davinci: iotable based ioremap() interception
This patch allows for a more flexible ioremap() interception based on iotable
contents.
With this patch, the ioremap() interception code can properly translate
addresses only after davinci_soc_info has been initialized. Consequently,
in soc-specific init functions, davinci_common_init() has to happen before any
ioremap() attempts. The da8xx init sequence has been suitably modified to meet
this restriction.
