Code cleanup and small improvements

Sets a callback that defines the maximum number of MSI applied to designware driver for future easiness and also as an example, since the callback currently defines the default value.

Does a code cleanup by replacing magic numbers without a easy meaning by a well known define that helps the human compreension.

Fix of the first characters on comments and debug messages to maintain coherency.

Replaces a division by 2 by a simple right shift rotation of 1 bit.

The patch set was made against Lorenzo's dwc-msi branch.
