firmware: ti_sci: Use system_state to determine polling

Browse source

[ Upstream commit 9225bcdedf ]

Commit b9e8a7d950 ("firmware: ti_sci: Switch transport to polled
mode during system suspend") aims to resolve issues with tisci
operations during system suspend operation. However, the system may
enter a no_irq stage in various other usage modes, including power-off
and restart. To determine if polling mode is appropriate, use the
system_state instead.

While at this, drop the unused is_suspending state variable and
related helpers.
