[PATCH 9/9] soc/qcom: Add REVID driver

[Konrad Dybcio <konradybcio@gmail.com>]

From: Xiaozhe Shi <xiaozhes@codeaurora.org>

Add the REVID device driver. The REVID driver will print out the PMIC
revision at probe time.

Signed-off-by: Xiaozhe Shi <xiaozhes@codeaurora.org>
[konradybcio@gmail.com: Fast-forward the driver from kernel 4.14 to 5.8,
convert binding to yaml]
