sevki c9e1dba412 chore(ci): setup github actions and workflows
setup CI/CD for kernel development
- added CodeQL for code scanning
- every pr is built as an image and is available for
  30days on https://oklinux.dev
- tagged and released on github for now

Kernel driver mc34vr500
=======================
Supported Chips:
* NXP MC34VR500
Prefix: 'mc34vr500'
Datasheet: https://www.nxp.com/docs/en/data-sheet/MC34VR500.pdf
Author: Mario Kicherer <dev@kicherer.org>
Description
-----------
This driver implements initial support for the NXP MC34VR500 PMIC. The MC34VR500
monitors the temperature, input voltage and output currents and provides
corresponding alarms. For the temperature, the chip can send interrupts if
the temperature rises above one of the following values: 110°, 120°, 125° and
130° Celsius. For the input voltage, an interrupt is sent when the voltage
drops below 2.8V.
Currently, this driver only implements the input voltage and temperature
alarms. The interrupts are mapped as follows:
<= 2.8V -> in0_min_alarm
>110°c -> temp1_max_alarm
>120°c -> temp1_crit_alarm
>130°c -> temp1_emergency_alarm
