Subject: [PATCH v2 0/2] misc: mei: Add support for IVSC device

The Intel visual sensing controller (IVSC) device is designed to
control the camera sharing between host IPU for media usage and
IVSC for context sensing (face detection).

IVSC is exposed to host as a SPI device and the protocol used
for communicating with host is MEI. This driver implements the
transport protocol and MEI hardware interfaces for IVSC device.

The firmware downloading for IVSC device is implemented as well.

v2:
  - change to `depends on INTEL_MEI_VSC_HW` for INTEL_MEI_VSC Kconfig
  - remove MODULE_ALIAS and add MODULE_DEVICE_TABLE in platform-vsc.c
