c982a053cd rp2040: circuitpython: Actually make dynamic PWM allocation work 
My initial testing was always done with PWM slice 0, so it didn't
matter that _PM_pwm_slice was never set to a nonzero value.  Limor tested
with the first pin as GPIO6, which led to use of slice 3 and after that
everything got sad really quickly.

Since Arduino doesn't use _PM_pwm_slice now, this means that
_PM_timerInit's implementation becomes unshared; because _PM_timerInit
nees to refer to _PM_PWM_ISR or _PM_timerISR, those newly require forward
(static) declarations.  That makes this change look bigger than it is.
The only "real" change is intended to be something like
```c
 #ifdef CIRCUITPYTHON
+void _PM_timerInit(void *tptr) {
+#if _PM_CLOCK_PWM
+  _PM_pwm_slice = (int)tptr & 0xff;
```

b58c78c9d2 core: _PM_resume: put address pins in known state 
Before this, using the "brightness" property in CircuitPython would cause the display to become jumbled.  Reproducer script for matrixportal:
```
import sys
import time
import random
from adafruit_matrixportal.matrix import Matrix

MATRIX = Matrix(bit_depth=1)
DISPLAY = MATRIX.display

sys.stdout.write("JUMBLED\nTEXT")
time.sleep(3)

while True:
    DISPLAY.brightness = 0
    DISPLAY.brightness = 1
    time.sleep(random.random())
```

After the fix there is only a slight flicker due to the time the display spends with zero brightness.

Thanks to @firepixie for the report!
