HID: intel-thc-hid: Intel-thc: Add more frequency support for SPI

The Nova Lake platform enhances THC with half divider capability for
clock division, allowing more granular frequency control for the THC
SPI port.

Supported frequencies include 50MHz (125MHz/2.5), 35MHz (125MHz/3.5),
and 10MHz (125MHz/8/1.5).
