Update tooling for custom kernels (#6)

Browse Source 
Improve support for custom device trees when kernel updates are received

* Modified make-trees.sh so that it builds for all installed kernels.
* A new script flash-latest.sh that copies the resulting .dtb files into the /etc/flash-kernel/dtbs/ override folder.

The build-trees README is updated for this, and shows how to configure flash-kernel to use the custom .dtbs.

Kernel upgrade should now go:

[after a new kernel upgrade is installed]
* Upgrade source: cd source && apt source linux-riscv
* Build dtb's: cd build-trees &&; ./make_dtbs.sh
* Install device tree via softlinks ./flash_latest.sh
* Reboot

# Alternate device tree Examples:
Each folder contains a `.dts` file and a README showing the GPIO pin mappings.
Copy the desired `.dts` file to the [build-trees](../build-trees) folder and follow the readme there to build the device-tree binaries.
## Use
Copy the desired `.dts` file(s) to the [build-trees](../build-trees) folder and follow the readme there to build the device-tree binaries.
There are instructions at the end of that document on how you can use a custom `.dtb` and make it permanent across reboots and kernel upgrades.
There are instructions at the end of that document on how to make this permanent across reboots and kernel upgrades, some example flash-kernel database entries are given below for convenience.
## Caveat
The issue with using these trees is that **if** the upstream device tree or includes is modified you need to manually rebuild these trees.
EG any changes to the upstream `sun20i-d1-mangopi-mq-pro.dts` source needs to be detected and applied too. You need to examine file histories to do this.
- Fortunately this should not be an issue in practice; the kernel *should* remain very stable going forward. Ubuntu 24.04.1 is a LTS release..
The authors personal advice is to use this only if needed; or as a learning excercise.

# A device tree for my LORA HAT..
* Brings a UART out for talking to the HAT
* Leaves pins `7`, `13` and `15` free since these are used to control and monitor the HAT
* Has the SPI interface in case I add a screen, and an I2C interface for talking to peripherals.

Notes:
- I2C pins 3,5,27 and 28 (PG13, PG12, PE17 and PE16) have 10K pullup resistors to 3v3
- The Status LED (PD18) is common with the LED_PWM pin on the DSI/LVDS output
