[PATCH v2] i2c: xiic: restore runtime PM teardown in remove to fix clk WARN flood

The devres conversion dropped the remove-time runtime PM trailer
(pm_runtime_disable + pm_runtime_set_suspended +
pm_runtime_dont_use_autosuspend). devm_pm_runtime_enable's release
action then calls pm_runtime_dont_use_autosuspend() while runtime PM
is still enabled, triggering an immediate runtime suspend: the suspend
callback clk_disable()s the clock that the devm_clk_get_enabled()
release is about to clk_disable_unprepare(), and every device teardown
WARNs in clk_core_disable() ("clkN already disabled").

Restore the trailer: with runtime PM disabled and the state forced to
suspended before devres runs, the suspend callback cannot fire and the
clock enable count stays balanced.
