busio (and presumably other base modules) do not do pin ownership, so it's possible to create multiple devices using the same pins, e.g.:

spi1 = busio.SPI(board.SCK,board.MOSI,board.MISO)
spi2 = busio.SPI(board.SCK,board.MOSI,board.MISO)

does not complain on nrf52. Or you could even create an SPI bus and and I2C bus on the same pins.

Symptoms noticed in #1088 (thanks @jerryneedell!)
