No dice, same exact problem.
But the patch is present downstream[1]:
commit c26727f853308dc4a6645dad09e9565429f8604f
Author: Loic Poulain <loic.poulain@linaro.org>

arm64: dts: apq8096-db820c: Increase load on l21 for SDCARD
In the same way as for msm8974-hammerhead, l21 load, used for SDCARD
VMMC, needs to be increased in order to prevent any voltage drop issues
(due to limited current) happening with some SDCARDS or during specific
operations (e.g. write).
Fixes: 660a9763c6a9 (arm64: dts: qcom: db820c: Add pm8994 regulator node)
Signed-off-by: Loic Poulain <loic.poulain@linaro.org>
so it's probably worth carrying it.
