meta-nicole: phosphor-dbus-interfaces: Add boot initiator mailbox interface

Add the xyz.openbmc_project.Control.Boot.Mailbox interface to allow
for provision of the boot initiator (such as Petitboot or UEFI) with
its specific parameters. This is based on IPMI 2.0 Table 28-14 'Boot
Option Parameters' parameter 7 'Boot initiator mailbox'.

+          The 24-bit IANA Private Enterprise Number for the company or organization
+          that has specified the boot initiator. This is a machine-specific
+          constant. The implementing application is responsible for setting
+          this to the proper machine-specific value (0x000000..0xFFFFFF)
+          according to https://www.iana.org/assignments/enterprise-numbers/enterprise-numbers.
+
+          The property is constant and is only set by the implementation
+          on startup.
+
+    - name: Data
+      type: array[byte]
+      description: >
+          The array of data bytes for the boot initiator to treat
+          in its specific way. This interface doesn't impose any
+          limitiations on the format or make any assumptions regarding
+          it. The boot initiator is responsible for parsing this array.
+
+          The size of the array is a constant depending on the requirements
+          set by the boot initiator used for a particular architecture or
+          a machine. The implementing application is responsible for setting
+          the size of this array to the proper value.
+
+          For conformance to the IPMI 2.0 specification, the size of the array
+          plus 3 (the size of IPMI 2.0 representation of IANA Enterprise Number)
+          must be a multiple of 16 with the minimum allowed size being 77
+          (5 x 16-byte blocks, minus 3) if mailbox is at all Supported.
+
+          For IPMI 2.0 this array is supposed to be split into 16-byte
+          blocks by the implementing service (block 0 being made of IANA PEN
+          plus first 13 bytes of this array). Please pay special attention
+          that this array does NOT include the IANA PEN needed for IPMI 2.0.
+          Only the actual PEN-specific data is stored here.
+
+          When partially written to, the remaining parts of this array
+          must not be automatically cleared. This is per IPMI 2.0
+          specification.
+
+          Other interfaces to the boot initiator (such as MCTP) may process
+          this array differently.
