isst_fill_platform_info fills platform specific information.
And it is the proper place to set platform specific callbacks, as done in
next patch.
As the platform specific callbacks are needed in all cases, including
isst_print_platform_information.
The best way to achieve both is to invoke isst_fill_platform_info
unconditionally, and make isst_print_platform_information leverage the
data already filled.

Punit id can also be retrieved from ISST_IF_GET_PHY_ID.
punit id is unique within a Package/Die, and together with Package id and
Die id, they can be used to refer to a specific SST power domain.
For current platforms, Punit id is always Zero. So no functional changes
are expected for the current platforms.

A regression has occurred in the hid-sensor code where a device
name string has not been initialized to 0, and ends up without
a NULL char and is printed with %s. This includes random binary
data in the device name, which makes its way into the ftrace output
and ends up crashing sleepgraph because it expects the ftrace output
to be ASCII only.
For example: "HID-SENSOR-INT-020b?.39.auto" ends up in ftrace instead
of "HID-SENSOR-INT-020b.39.auto". It causes this crash in sleepgraph:
File "/usr/bin/sleepgraph", line 5579, in executeSuspend
for line in fp:
File "/usr/lib/python3.10/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position
1568: invalid start byte
The issue is present in 6.3-rc1 and is described in full here:
https://bugzilla.kernel.org/show_bug.cgi?id=217169
A separate fix has been submitted to have this issue repaired, but
it has also exposed a larger bug in sleepgraph, since nothing should
make sleepgraph crash. Sleepgraph needs to be able to handle binary
data showing up in ftrace gracefully.
Modify the ftrace processing code to treat it as potentially binary
and to filter out binary data and leave just the ASCII.
