Connection tear down is being reworked, and the SVC quiescing operation
is going away.
Let's remove this operation now along with the coupled second ping from
our intermediate tear down implementation.
This both avoids unnecessary noise in the logs resulting from the fact
that the SVC side of the quiescing operation was never merged, and
speeds up connection tear down slightly.
Testing done: Tested on EVT2 using runtime PM.

The S3 firmware and S3-BFU firmware images will be named like this going
forward:
S3: ara_00000126_00001001_fffe0001_ffe70018_s3f.tftf
S3-BFU: ara_00000126_00001001_fffe0001_ffe70018_s3_bfu.tftf
But the current naming for S2 loader image is:
ara_00000126_00001001_fffe0001_ffe70018_02.tftf
It makes sense to use similar encoding for all three packages and so it
should be named as:
ara_00000126_00001001_fffe0001_ffe70018_s2l.tftf
Because the boot stage is passed from ES3 bootrom, we can't change its
value now. But the string created to match the package name is created
in bootrom.c and that is the only string we create from bootrom.c.
Update bootrom.c to use "s2l" instead of "02" in the package name.

gb_timesync_schedule_synchronous() is currently making a synchronous
FrameTime synchronization happen. It does a wait_event_interruptible() and
then goes to check the status of the state-machine. Occasionally the state
indicates PING - which is a completely valid state and should result in a
result code of 0 not -EAGAIN. This patch fixes by making
__gb_timesync_get_status() return 0 instead of -EAGAIN for the PING state.
