[ Upstream commit f9c730ede7d3f40900cb493890d94d868ff2f00f ]
DG1 does some additional pcode/uncore handshaking at boot time; this handshaking must complete before various other pcode commands are effective and before general work is submitted to the GPU. We need to poll a new pcode mailbox during startup until it reports that this handshaking is complete.
The bspec doesn't give guidance on how long we may need to wait for this handshaking to complete. For now, let's just set a really long timeout; if we still don't get a completion status by the end of that timeout, we'll just continue on and hope for the best.
v2 (Lucas): Rename macros to make clear the relation between command and result (requested by José)

You also need to sign-off on a patch you submit for inclusion anywhere, right?
Please resend this series with that added so that we can queue them up.
