hisilicon-opensdk: bump to 7f3697d, SP2305 exposure written every frame

[openipc-ai]

What

Bumps hisilicon-opensdk from 4e5359b to 7f3697d, bringing in OpenIPC/openhisilicon#255.

Why

The SP2305/OV2735 sensor driver (hi3516ev200 family, gk7205v200 family) wrote the exposure registers only when auto-exposure changed its value. A corrupted value therefore stayed in the sensor.

Running a sensor probe on a streaming camera corrupted it: ipctool -s or ipcinfo --short-sensor wrote 0xF1 into the exposure high byte. In a bright scene the picture went white and stayed white until the streamer restarted. This is the random white-out in OpenIPC/majestic#295.

• The driver now rewrites the exposure every frame (except during pixel calibration), so any such corruption is undone on the next frame.
• The probe itself is fixed in sensors: probing a streaming SP2305 no longer turns its picture white ipctool#238. This firmware builds ipctool at HEAD, so that fix needs no bump here.

Scope

The range has one other commit, #254. It only changes the NPU test tools (xmedia_npu/test), which this package does not build. The only shipped file that changes is libsns_sp2305.so.

Tested

On an hi3516ev300 with an SP2305/OV2735, with the driver from #255:

• the exposure register corrupted to 0xF1: picture recovered within 0.3 s;
• ipctool -s run while streaming: picture recovered within 3 s;
• the old driver stayed white in both cases.

High-Level Assessment

Pinning the upstream fix is preferable to carrying a local driver patch: it delivers the corrected sensor library through the existing build and install path without maintaining a fork. The additional upstream NPU test-tool change is not built by this package.

• Changes the fetched upstream revision from 4e5359b to 7f3697d. The new revision includes the SP2305/OV2735 driver fix that rewrites exposure every frame outside pixel calibration; the package's build and install rules are unchanged.
