Stefan Lippers-Hollmann f70e11cd97 ipq806x: g10: case-insensitive qcom-smem partitions
The out-of-tree qcom-smem patches traditionally displayed mtd partition names
in upper case, starting with the new mainline qcom-smem support in kernel v5.10,
it switches to normalizing the partition names to lower case.
