* [Core] Rework PS/2 driver selection
Enabling and selecting PS/2 driver was using old approach,
so it was reworked to current approach, inspired by Serial
and WS2812 driver selections.
* [Keyboard] Update keyboards using PS/2 to use new PS/2 driver selection
* [Docs] Update PS/2 documentation to use new PS/2 driver selection
* Fix indentation
* [Core] Add PS2 to data driver
* Fix oversight in property name

* Add ARRAY_SIZE and CEILING utility macros
* Apply a coccinelle patch to use ARRAY_SIZE
* fix up some straggling items
* Fix 'make test:secure'
* Enhance ARRAY_SIZE macro to reject acting on pointers
The previous definition would not produce a diagnostic for
```
int *p;
size_t num_elem = ARRAY_SIZE(p)
```
but the new one will.
* explicitly get definition of ARRAY_SIZE
* Convert to ARRAY_SIZE when const is involved
The following spatch finds additional instances where the array is
const and the division is by the size of the type, not the size of
the first element:
```
@ rule5a using "empty.iso" @
type T;
const T[] E;
@@
- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)
@ rule6a using "empty.iso" @
type T;
const T[] E;
@@
- sizeof(E)/sizeof(T)
+ ARRAY_SIZE(E)
```
* New instances of ARRAY_SIZE added since initial spatch run
* Use `ARRAY_SIZE` in docs (found by grep)
* Manually use ARRAY_SIZE
hs_set is expected to be the same size as uint16_t, though it's made
of two 8-bit integers
* Just like char, sizeof(uint8_t) is guaranteed to be 1
This is at least true on any plausible system where qmk is actually used.
Per my understanding it's universally true, assuming that uint8_t exists:

* Run qmk-format on core C files touched in this branch

* Add an ez_maker directpins for rp2040
This allows all exposed pins on the Raspberry Pi Pico to be used
as up to 26 individual keys. Keys use a common ground arrangement.
The firmware is also expected to work on generic RP2040 boards, check
manufacturer pinout diagrams or use trial and error to find out the GP#s
of the pins.
