Move some led drivers to common folder

[zvecr]

Description

Not 100% sold on the current "parent folder that only contains 2 files" paradigm. What I would like to see would be something like...

drivers/led/apa102.h
drivers/led/aw20216.h
drivers/led/is31fl3731.h
  ...
drivers/led/is31fl3737.c

However it does at least have some value for issi right now due to the amount of tiles inc. led/rgb variant drivers.

I have thought (not very hard) about the logistics and worth of moving to a more traditional include/ and src/-style hierarchy. But that's probably a lot of work that can probably only be done once things like tmk_core/ are assimilated into quantum/.

Ideally, I'd like to see the ISSI drivers in there too, but this is great.

I was planning to, as part of this PR but still not sure on the issi parent folder.

Done! Apologies in advance for the extra files that have to be reviewed...

May be worth putting the ISSI drivers into drivers/led/issi/.

That hass been on the cards for the lifetime of this PR, and no one spoke up about it so i went with my personal preference.

What i want to avoid is the "vendor" folder situation that happened with the other 2 drivers that I've moved. A folder with just 2 files inside it, which had been copied as some form of standard due to the precedence set with the issi folder.

[fauxpark]

The ISSI drivers warrant their own directory due to the sheer number of them, whereas anything directly under drivers/led/ can be seen as "miscellaneous", until we collect enough like ones to group them together.

I personally dont see the value, but if it helps get this across the line then i will make the change, Just a little disappointed that it was up for grabs and its only after ive made the change that i now have to do more work.

[fauxpark]

I don't really see where you mentioned this.

[zvecr]

In the PR description. Doesnt matter anyway, ive moved the files keeping the issi folder.

[fauxpark]

Wasn't really clear to me what you were saying there, the issi folder isn't a "parent folder that only contains 2 files" but I understand now.

[drashna]

Personally, I'm fine with throwing everything in /drivers/led, since the naming helps sort them out. But either way is absolutely fine, IMO.
