[XEN PATCH 01/13] xen/x86: fixed violations of MISRA C:2012 Rule 7.2

[Simone Ballarin <simone.ballarin@xxxxxxxxxxx>]

From: Gianluca Luparini <gianluca.luparini@xxxxxxxxxxx>

The xen sources contains violations of MISRA C:2012 Rule 7.2 whose headline 
states:
"A "u" or "U" suffix shall be applied to all integer constants that are 
represented in an unsigned type".

I propose to use "U" as a suffix to explicitly state when an integer constant 
is represented in an unsigned type.
For homogeneity, I also added the "U" suffix in some cases that the tool didn't 
report as violations.
