Subject: [PATCH v3 3/3] arm64: dts: qcom: qrb4210-rb2: Increase load on l22 and l24 for uSD and eMMC

Increase the l22 and l24 load used for uSD and eMMC VMMC.
These need to be increased in order to prevent any voltage drop
issues due to limited current happening during specific operations
(e.g. write).
