Subject: [PATCH v3 4/5] ARM: dts: qcom: pm8941: Add nodes for QCOM SPMI Flash LEDs

Add nodes for Qualcomm's SPMI Flash LEDs present in PM8941. There are
two white LEDs which can be used as flash or torch.

Signed-off-by: Nícolas F. R. A. Prado <nfraprado@...labora.com>

Changes in v3:
- Disabled node
- Removed LED configuration (moved to hammerhead dts in patch 5)

Changes in v2:
- Moved from hammerhead dts to pm8941 dtsi, as it was this way downstream
- Now using values from leds-qcom-spmi-flash.h
