misc: mrvl-cn10k-dpi: add Octeon CN10K DPI administrative driver
Adds a misc driver for Marvell CN10K DPI(DMA Engine) device's physical
function which initializes DPI DMA hardware's global configuration and
enables hardware mailbox channels between physical function (PF) and
it's virtual functions (VF). VF device drivers (User space drivers) use
this hw mailbox to communicate any required device configuration on it's
respective VF device. Accordingly, this DPI PF driver provisions the
VF device resources.
At the hardware level, the DPI physical function (PF) acts as a management
interface to setup the VF device resources, VF devices are only provisioned
to handle or control the actual DMA Engine's data transfer capabilities.
