The main function is to obtain voltage and current, currently used for
testing the input voltage and input current of the RK1820 small board on
the RK3588 to determine the current load.

During the long-term loop playback test of videos stored in the
USB flash drive, it was found that the Teclast CoolFlash drive
(idVendor=346d, idProduct=5678) disconnects abnormally, and the
serial port reports the following error messages.

Adding this quirk to limit max_sectors to 64 sectors to avoid issue

Because the call:
platform_set_drvdata(pdev, am_d);
in aoa_mmap_probe() is overwritten by the subsequent call:
platform_set_drvdata(pdev, amw_d);
therefore, the am_d handle needs to be saved separately. Also, previously allocated IRQ and
platform resources must be released.
And, fix the issue where repeated insmod operations couldn't be performed due to resource usage.
After successfully executing the command `insmod rk_aoa.ko` for the first time,
executing `rmmod rk_aoa` to uninstall the file and then executing `insmod rk_aoa.ko`
again will result in the following error:
----
[ 93.352370] platform 208b0000.aoa: can't request region for resource [mem 0x208b0000-0x208b0fff]
[ 93.352401] aoa-middleware aoa_middleware: probe rockchip aoa failed: -16
[ 93.352411] aoa-middleware: probe of aoa_middleware failed with error -16
----
Furthermore, the pdev functions for aoa_drv and lp_rkdma are manually probed via
aoa_middleware and cannot be automatically released via the devm mechanism.
Therefore, you must manually allocate resources in the probe function and release
them manually in the remove function.

Some master device resume early but the iommu has not yet resume, which
will cause the iommu to be inaccessible.
So set LATE_SYSTEM_SLEEP_PM_OPS for iommu pm ops, which will resume early and suspend late.

In kernel 6.1 and later versions, the property 'clk-trcm' has been updated:
rockchip,clk-trcm -> rockchip,trcm-sync-tx/rx-only
Not all products' DT have been updated to use the new property. Therefore,
still support for old property for now, and a prompt is logged to suggest
to adopt the new property.
The old property will be removed in a future version.
Log:
Deprecated property 'rockchip,clk-trcm', please use 'rockchip,trcm-sync-tx/rx-only' in DT
