Use cyw43_delay_ms() in cyw43_spi_reset() instead of sleep_ms() (#2431)

Browse source 
Since cyw43_spi_reset() may be executed from an async context, we
should use cyw43_delay_ms() instead of sleep_ms(). This is particularly
a problem when using the async_context_threadsafe_background backend,
because sleep_ms() will assert in an ISR.
