mc13xxx: make driver-provided SPI frequency overridable
The preset SPI frequency for mc13xxx PMIC introduced with patch 6e18b3a48ee4
("mc13xxx: Define maximum SPI clock frequency global to driver") is not
desirable or working on all boards. Provide a possibility to override
the default SPI max_speed_hz from board code.
