Fixes RP2040 busio.SPI() fails to note initial SPI frequency #5836.

Tested on QT Py RP2040:

>>> import busio,board
>>> spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
>>> print(spi.frequency)
250000
>>> spi.try_lock()
True
>>> spi.configure(baudrate=200000)
>>> print(spi.frequency)
244140
>>> spi.configure(baudrate=250000)
>>> print(spi.frequency)
250000
>>> spi.configure(baudrate=25000)
>>> print(spi.frequency)
27126
