stm32/pin: Change remaining uses of "af" to "alt".

Browse Source 
The keyword "af" has been deprecated for some time and "alt" should be used
instead (but "af" still works).

For the pyboard, x3_af would contain:
[Pin.AF1_TIM2, Pin.AF2_TIM5, Pin.AF3_TIM9, Pin.AF7_USART2]
Normally, each peripheral would configure the af automatically, but sometimes
the same function is available on multiple pins, and having more control
is desired.
Normally, each peripheral would configure the alternate function automatically,
but sometimes the same function is available on multiple pins, and having more
control is desired.
To configure X3 to expose TIM2_CH3, you could use::
pin = pyb.Pin(pyb.Pin.board.X3, mode=pyb.Pin.AF_PP, af=pyb.Pin.AF1_TIM2)
pin = pyb.Pin(pyb.Pin.board.X3, mode=pyb.Pin.AF_PP, alt=pyb.Pin.AF1_TIM2)
or::
pin = pyb.Pin(pyb.Pin.board.X3, mode=pyb.Pin.AF_PP, af=1)
pin = pyb.Pin(pyb.Pin.board.X3, mode=pyb.Pin.AF_PP, alt=1)
