Alarm support for ISL12057 + RFC dt property

Hi,

Changes since v0:

- Basic alarm support is now the first patch of the series with nothing fancy in it: as per Uwe's request, all the "Chip IRQ#2 is not routed to the SoC but device can still be woken up with the alarm" is in the second patch. Uwe, can you review that one, so that Andrew can then merge it if it is ok?
- Second patch has simple changes going on top of first patch to support the use case for current in-tree users, i.e. ReadyNAS 102, 104 and 2120. It's a simple property with complete documentation about what it does and does not.
- Third and last patch add that property to 102, 104 nd 2120 .dts files (in a single patch as suggested by Jason)

Comments welcome,

Cheers,

a+
