Because the matrix scanning is slower for splits, in general,
the frequent updating of the OLEDs can slow down the matrix scanning.
To help prevent that, set the update interval for the OLEDs to not
update as frequently.
* ws2812: Fix number of nops for AVR at 8 MHz
When trying to calculate the number of nops for AVR running at 8 MHz,
the value of `w3` is expected to be negative; however, because `F_CPU`
is defined in tmk_core/avr.mk with the `UL` suffix, the preprocessor
performs its calculations using `unsigned long`, getting a very large
positive number instead of the expected negative number; this then
results in generating code with a huge number of nops. Fix the broken
calculations by performing a comparison before subtraction, so that the
unsigned number wraparound does not occur.
The keyboard which triggers the problem is `handwired/promethium`; the
buggy code silently compiles, but the resulting timings would be
completely wrong.
* ws2812: Clean up the code after the 8 MHz fix
Remove old code which was unsuccessfully trying to clamp negative w1, w2
and w3 values to 0, and set w1_nops, w2_nops and w3_nops directly.

* Rewrite APA102 support
The APA102 source was broken by commit 16a15c1cfc as it did not include the
quantum header. This commit addresses that, as well as other issues with
transferring bytes over the SPI interface, i.e. it was not setting the
clock pin back to low after sending a bit.
The deviation when sending the end frame is kept, but updated to the
latest from the referenced project.
Finally, these changes expose the global LED brightness parameter
of the APA102. Brightness values are configurable through
`APA102_DEFAULT_BRIGHTNESS` and `APA102_MAX_BRIGHTNESS`.

* Fix dirtying in oled_write_pixel()
Set the dirty bit for the block only if oled_write_pixel() actually
changed the buffer state. Without this check oled_write_pixel() could
not be used inside the oled_task_user() code using the “redraw always”
style, because the blocks touched by oled_write_pixel() would always
appear dirty, and oled_render() would not proceed beyond the first such
dirty block.
* Fix oled_write_pixel() with 90/270 degree rotation
Use oled_rotation_width instead of OLED_DISPLAY_WIDTH, so that a rotated
display would be handled correctly.
* Fix compilation with custom OLED_BLOCK_COUNT and OLED_BLOCK_SIZE
Some OLED sizes (e.g., 64×48) may require a nonstandard value of
OLED_BLOCK_COUNT. The documentation says that this value may be
redefined in config.h, but actually trying to redefine it caused a
compile error, because the macro was redefined in oled_driver.c.
Make the OLED_BLOCK_COUNT definition in oled_driver.c respect any
user override, and do the same for OLED_BLOCK_SIZE just in case.
* Fix handling of out-of-range bits in oled_dirty
If a custom OLED_BLOCK_COUNT value is specified, some bits in oled_dirty
may not correspond to existing blocks; however, if those bits are set
somewhere (e.g., by code with sets oled_dirty to ~0 or even -1),
oled_render() would try to handle them and could access memory beyond
oled_buffer and perform hardware operations with out of range values.
Prevent this by masking off unused bits in oled_render(), and also avoid
setting those bits in other functions.
* Fix potentially wrong dirtying in oled_write_char()
oled_write_char() tried to mark the position just beyond the written
character as dirty; use (OLED_FONT_WIDTH - 1) to dirty the last position
still belonging to the character instead.
* Fix `#define OLED_BLOCK_TYPE uint32_t` on AVR
Using uint32_t as OLED_BLOCK_TYPE did not work properly on AVR, because
some bit shifts were performed using 16-bit int. Add explicit casts to
OLED_BLOCK_TYPE to those shifts.
* Fix issue with data transfer of CS1_SW7 to CS18_SW7.
* Fix issue with handling of scaling register buffer's dirty flag.
* Remove unused extern declaration.
* Compaction of struct is31_led utilizing bit fields.
