f730eceb42 drm/tinydrm/mi0283qt: Let the display pipe handle power 
It's better to leave power handling and controller init to the
modesetting machinery using the simple pipe .enable and .disable
callbacks. Remove unused mipi_dbi_pipe_enable().

24e05e7a82 drm/tinydrm/mi0283qt: Remove ili9341.h 
No need for a public header file for the command macros.
Just include the necessary ones in the driver.

Also use the MIPI_DCS_PIXEL_FMT_16BIT macro.

d3820952ea drm/tinydrm: Use drm_fb_cma_fbdev_init_with_funcs/fini() 
Use drm_fb_cma_fbdev_init_with_funcs() and drm_fb_cma_fbdev_fini() which
relies on the fact that drm_device holds a pointer to the drm_fb_helper
structure. This means that the driver doesn't have to keep track of that.
Also use the drm_fb_helper functions directly.
Remove todo entry.

95a0cfe98c drm/tinydrm: Drop driver registered message 
No need to put out a driver registered message since drm_dev_register()
does that now. SPI speed is an important metric when dealing with
display problems, so retain that info.

This removes the call to mipi_dbi_init() from mipi_dbi_spi_init() so that
drivers can have a driver-specific implementation if needed.
