VirtQueue: OMAP5: Poll for VDEV status in VirtQueue_startup()
This resolves a race condition where the first slave RPMSG send would block
in a non-task context on a Semaphore_pend(), when the slave loads faster than
than the host can prime the send buffers in the vring to the host.
This patch implements the solution for OMAP5 separately.
