Hugo VilleneuveandGreg Kroah-Hartman 7ce7425537 serial: sc16is7xx: set safe default SPI clock frequency ...

commit 3ef79cd141 upstream.

15 MHz is supported only by 76x variants.

If the SPI clock frequency is not specified, use a safe default clock value
of 4 MHz that is supported by all variants.

Also use HZ_PER_MHZ macro to improve readability.
