When Linux is master of BAM, it can directly read registers to know number
of supported execution enviroments, however when its remotely controlled
reading these registers would trigger a crash if the BAM is not yet
intialized/powered up on the remote side.

This patch adds new binding num-ees to specify supported number of
Execution Environments when BAM is remotely controlled.

The correct split is the binding changes in 1 patch. Driver changes
separate.

Sure, Will Split it in next version.

This one needs a vendor prefix as it is not a common property.

Make sense, I will change it in next version.
