[PATCH V2] dtc: Basic integer expressions

[Jon Loeliger]

> Written by David Gibson <david at gibson.dropbear.id.au>. Additions by me:
> * Ported to ToT dtc.
> * Renamed cell to integer throughout.
> * Implemented value range checks.
> * Allow L/UL/LL/ULL suffix on literals.
> * Enabled the commented test.

> v2:
> * s/cell/integer/ throughout.
> * Allow signed-extended values to pass the overall cell range check.
> * Allow L/UL/LL/ULL suffix on literals. This is purely for compatibility
>   with C, and has no effect on dtc's processing.
> * Enabled the 3 disabled tests.
> 
> I'm not sure if the literal suffix handling is hacky or not...
