[PATCH v9 2/2] arm64: dts: qcom: sdm845-google: Enable PMI8998 camera flash LEDs

[David Heidelberg via B4 Relay <devnull+david.ixit.cz@kernel.org>]

From: David Heidelberg <david@ixit.cz>

Enable the PMI8998 flash LED block and describe two white flash LEDs
used for the rear camera.

Configure the LED in flash mode with hardware limits matching the
original device configuration, including maximum current and timeout.

In contrary to downstream, we can control both LEDs separately.
