drm/tiny: Add MIPI DBI compatible SPI driver 
Add a driver that will work with most MIPI DBI compatible SPI panels.
This avoids adding a driver for every new MIPI DBI compatible controller
that is to be used by Linux. The 'compatible' Device Tree property with
a '.bin' suffix will be used to load a firmware file that contains the
controller configuration.

Example (driver will load sainsmart18.bin):

display@0 {
	compatible = "sainsmart18", "panel-mipi-dbi-spi";
...
};

v5:
- kconfig: s/DRM_KMS_CMA_HELPER/DRM_GEM_CMA_HELPER/ (Sam)
- kconfig: Add select VIDEOMODE_HELPERS (Sam)
- kconfig: Add wiki url in the description (Sam)
- Split out and use of_get_drm_panel_display_mode()(Sam)
- Only use the first compatible to look for a firmware file since the
  binding mandates 2 compatibles.
- Make having a firmware file mandatory so we can print an error
  message if it's missing to improve the user experience. It's very
  unlikely that a controller doesn't need to be initialized and if
  it doesn't, it's possible to have a firmware file containing only
  a DCS NOP.

v4:
- Move driver to drm/tiny where the other drivers of its kind are located.
  The driver module will not be shared with a future DPI driver after all.

v3:
- Move properties to DT (Maxime)
- The MIPI DPI spec has optional support for DPI where the controller is
  configured over DBI. Rework the command functions so they can be moved
  to drm_mipi_dbi and shared with a future panel-mipi-dpi-spi driver

v2:
- Drop model property and use compatible instead (Rob)
- Add wiki entry in MAINTAINERS

help
This is a KMS driver for emulated cirrus device in qemu.
It is *NOT* intended for real cirrus devices. This requires
the modesetting userspace X.org driver.
Cirrus is obsolete, the hardware was designed in the 90ies
and can't keep up with todays needs. More background:
https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/
Better alternatives are:
- stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+)
- qxl (DRM_QXL, qemu -vga qxl, works best with spice)
- virtio (DRM_VIRTIO_GPU), qemu -vga virtio)

DRM driver for simple platform-provided framebuffers.
This driver assumes that the display hardware has been initialized
by the firmware or bootloader before the kernel boots. Scanout
buffer, size, and display format must be provided via device tree,
UEFI, VESA, etc.
On x86 BIOS or UEFI systems, you should also select SYSFB_SIMPLEFB
to use UEFI and VESA framebuffers.
