This patch fixes a possible timeout in poll loop without actually
checking the register before return. In theory the there is a possibility
of loop being scheduled after a long lock/delay, which would then force
the loop to exit without actually checking the register.

In order to deal with offsets differences between MDP5 v1.3 and
earlier versions, dynamic offsets are introduced.
At runtime, MDP version is read to find out which hardware
configuration is embedded on the target. Once this is found out,
these dynamic offsets are set through global variables
This patchset is intended to be used on top of Rob's wip changes in the
'variable-bases' branch. Dynamic offsets are introduced for MDP5 register
description in order to support multiple versions (v.1.3 added here).
