[PATCH v2 0/4] Make PL031 interrupt optional

[Russell King - ARM Linux]

There are some boards out there which have a PL031 RTC, but its
interrupt is not wired up.  To support these, we need the PL031
to support the primecell without interrupts.

When no interrupt is present, there's little point exposing the
RTC's alarm capabilities, so we omit the alarm-related function
calls - the RTC merely becomes a source of time-of-day.

This patch series cleans up the pl031 driver a little, and adds
support for this configuration.
