[PATCHv4 0/2] Adding driver for Xilinx LogiCORE IP mailbox.

[Moritz Fischer <moritz.fischer@ettus.com>]

This patchset adds mailbox framework integration for the Xilinx LogiCORE IP
mailbox.  The Xilinx LogiCORE IP mailbox is a fpga softcore that allows
interprocessor communication between AXI4 stream / memory mapped
processors.

Changes from v3:
- Stylistic changes
- Changed reg size in dts to 0x100

Changes from v2:
- Fixed error condition for IRQ from >= 0 to > 0
- Fixed clock enable
- Cleaned up docs

Changes from v1:
- Added common clock framework support
- Deal with IRQs that happend before driver load,
  since HW will not let us know about them when we enable IRQs

Changes from v0:
- Several stylistic issues
- Dropped superfluous intr_mode member
- Really masking the IRQs on mailbox_shutdown
- No longer using polling by accident in non-IRQ mode
- Swapped doc and driver commits

Happy hacking,

Moritz
