serial: sc16is7xx: set safe default SPI clock frequency
[ Upstream commit 3ef79cd1412236d884ab0c46b4d1921380807b48 ]
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.
