drm/evdi: Drop cursor 64x64 limit

Instead of copying cursor during cursor_set event we vmap gem object
and read directly from gem object. Hence there is no need for cursor
buffer allocation and cursor buffer limits.

drm/evdi: Add enable_cursor_blending module param

Parameter is used to enable or disable cursor compositioning on user
supplied framebuffer during EVDI_GRABPIX ioctl.

This adds possibility to get framebuffer content without

By default cursor compositioning is enabled.
