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.

While handling PRCM IRQs, mask out interrupts that are not enabled in
PRM_IRQENABLE_MPU. If these are not masked out, non-enabled
interrupts are caught, a WARN() is printed due to no 'handler' and the
events are cleared. In addition to being noisy, this can also
interfere with independent polling of this register by SR/VP code.
This was noticed using SmartReflex transitions which cause the VPx_*
interrupts to be handled since they are set in PRM_IRQSTATUS_MPU even
but not enabled in PRM_IRQENABLE_MPU.
