qcom: Enable AP_RST_L interrupt on sysjump to RW
qcom: Enable AP_RST_L interrupt on sysjump to RW

The AP_RST_L interrupt is default disabled. It avoids unnecessary power
signal messages in G3/S5 as the signal is floating (no power). The
interrupt is then enabled during S5->S3 and disabled during S3->S5.

However, when sysjump to RW, the interrupt is back to default disabled.
This causes the `apreset` command fails to sample the AP_RST_L signal
and forces to execute a cold reboot sequence.

We should enable AP_RST_L interrupt when the initial power state is S0,
the sysjump to RW scenario.

BRANCH=Trogdor
BUG=b:185551931
TEST=Tested on Coachz, reboot EC, sysjump to RW, perform `apreset` which
executes a warm AP reboot.
