drm/msm/a2xx: Add hangcheck progress detection

A2xx has no progress callback, so any submit still running when the
hangcheck timer expires is declared hung, no matter whether the CP is
advancing. A false lockup is particularly expensive here: a2xx recovery
is unreliable, and a second reset shortly after the first one leaves
a2xx_hw_init() failing for good, so everything submitted afterwards
fails as well.

Compare the CP IB1/IB2 base and remaining size between timer
expirations, like a6xx does.
