gsp-phys: use the reference default for a zero sequencer poll timeout

A zero REG_POLL timeout dword is the reference's GPU_TIMEOUT_DEFAULT
sentinel: the reference substitutes the platform default (microseconds;
4 s in graphics mode, the default platform) before waiting. The executor
clamped zero to the 1 us floor, i.e. one jiffy, so a poll that was not
already satisfied failed the boot in 1 ms.

The live 0x1002 sequencer element contains exactly one REG_POLL with
timeout=0 (addr 0x110040); substitute the 4 s graphics-mode default and
then keep the existing 1 us .. 10 s clamp.
