Light all leds when flash is empty.

Closes UltimateHackingKeyboard/firmware#971

Tested only with uhk80.

I ran nrfjprog --eraseall on both halves, then flashed the firmware. This is the result:

Some of the left LEDs are yellow, and all of the right LEDs are dim.

[kareltucek]

Ah. I naively assumed the left half leds to be controlled by right side 🤦.

Will fix that in a minute.

[kareltucek]

Should be fixed.

[mondalaci]

The UHK 80 works as expected.

But UHK 60 LEDs are lit according to their functional backlighting colors. User config is set. Hardware config is unset. Uninitialized EEPROM seems to contain 0xff, not 0x00, which may be the issue.

[kareltucek]

User config is set.

This is the issue. I didnt read the specification carefully and require both regions to be empty.

[kareltucek]

Please test now.

[mondalaci]

Almost perfect, but the LEDs of the left ANSI Shift are disabled.

[kareltucek]

Aargh. Is that important? Switches can't be tested at this point anyways.

(If so, I will have to figure out another way to implement that...)

Edit: nevermind, will deal with it.

[mondalaci]

At this stage, switches aren't even put into the PCB. The operator must see whether all LEDs work.

[kareltucek]

Here you go.
