arm64: dts: apq8096-db820c: Increase load on l21 for SDCARD

commit e38161bd325ea541ef2f258d8e28281077dde524 upstream.

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).
