[PATCH V3 0/4] mailbox: xgene: Add support for APM X-Gene SoC Queue Manager/Traffic Manager

[Ravi Patel]

This patch adds support for APM X-Gene SoC Queue Manager/Traffic Manager.
 QMTM is required by APM X-Gene SoC Ethernet, PktDMA (XOR Engine) and
 Security Engine subsystems. All subsystems communicate with QMTM using
 messages which include information about the work to be performed and
 the location of associated data buffers.

V3:
 * Switch to mailbox framework
 * Add support for little and big endian kernel
 * Change virt_to_phys function call to dma_zalloc_coherent

V2:
 * Adding COMPILE_TEST dependency for QMTM in Kconfig
 * Updated license banner as per review comments
 * Fixed alignment for macros
 * Changed EXPORT_SYMBOL to EXPORT_SYMBOL_GPL

V1:
 * inital version
