Alessandro Gatti 86c71a0307 esp32/machine_hw_spi: Reject invalid number of bits in constructor. ...

This commit adds an extra bit of parameters validation to the SPI bus
constructor on ESP32.  Passing 0 as the number of bits would trigger a
division by zero error when performing read/write operations on an SPI
bus created in such a fashion.

Fixes issue #5910.
