As there's no known hardware capability about querying vblank on the
7A1000 display controller, setting get_vblank_timestamp will mislead the
kernel about the support of DC-backed high precision vblank query.
Drop this function pointer in the CRTC function table for 7A1000.
This solves a kernel warning when booting Linux 7.0-rc3 on a
3A4000+7A1000 Haier Boyue G51 laptop (with injected EDID for replicating
the display timing set by the firmware).
