[PATCH v2 0/3] firmware: stratix10-rsu: expose QSPI flash size and erase size from firmware

[tze.yee.ng@altera.com]

From: Tze Yee Ng <tze.yee.ng@altera.com>

This series lets user space read per-device QSPI flash size and erase
size for the Intel Stratix 10 RSU driver, using the existing service
layer SMC path.

Patch 1 documents the new sysfs attributes (size0-size3 and
erase_size0-erase_size3).

Patch 2 implements COMMAND_RSU_GET_DEVICE_INFO in the RSU and service
drivers, caches up to four devices in the driver, and adds the sysfs
files.

Patch 3 fixes probe/remove teardown after the async client is registered:
remove the async client before freeing the SVC channel so async state
is not leaked. It also corrects probe return values on the affected
error paths.

Changes in v2:
- No code changes in all patches, only documentation updates to fix commit
 title and description in Patch 3.
