gpu: host1x: Export host1x_syncpt_read()
This function is used to read the current value of the syncpt and is useful in situations where drivers don't schedule work and wait for the syncpoint to increment. One particular use-case is using the syncpoint as a VBLANK counter. Signed-off-by: Thierry Reding <treding@nvidia.com>
