drivers/nrf24l01: Update to work on newer ports, using machine, utime.
drivers/nrf24l01: Update to work on newer ports, using machine, utime.

Changes made are:
- Use the time module in place of the pyb module for delays.
- Use spi.read/spi.write instead of spi.send/spi.receive.
- Drop some non-portable parameters to spi and pin initialization.

Thanks to @deshipu for the original patch.
