dt-bindings: mfd: Add Broadcom's MISC block 



Broadcom's MISC is an MFD hardware block used on some of their SoCs like
bcm63xx and bcm4908. At this point only PCIe reset is fully understood
and documented. More functions may be added later.

  Broadcom's MISC is a hardware block used on some SoCs (e.g. bcm63xx and

  reset, UniMAC control and more.
