Rule 7.2 states: "A u or U suffix shall be applied to all integer
constants that are represented in an unsigned type".

Some PM_* constants are unsigned quantities, despite some
of them being representable in a signed type, so a 'U' suffix
should be present.

No functional change.

This fix is needed in order to keep the rule clean when the
Xen configuration under static analysis is changed later in patch 3
of this series.

Only PM_RSTC_WRCFG_CLR is strictly needed to conform to the rule,
but the other constants have a 'U' added for consistency. PM_RSTC
and PM_WDOG are used as offsets, so in principle they can be negative,
therefore they are left as is.
