tsc_freq_mhz() had a static table of Intel CPU families and crystal
clock, but it is possible to calculate the crystal clock speed dynamically,
and this is preferred over hardcoded table.
On SKL/KBL/CML CPUID.15h.ecx = nominal core crystal clock = 0 Hz
hence we had to use static table to calculate crystal clock.
Recommendation is to make use of CPUID.16h where crystal clock frequency
was not reported by CPUID.15h to calculate the crystal clock.

Currently SPI bus id is used to map to the controller in order to set
the controller state. In certain platforms SPI bus id might not be
exactly the same as GSPI bus id. For example, in Intel platforms SPI bus
id 0 maps to fast spi i.e. SPI going to the flash and SPI bus id 1 .. n
map to GSPI bus id 0 .. n-1. Hence using SPI bus id leads to mapping to the
GSPI controller that is not enabled. Use the GSPI id bus so that the right
controller is set to active state. This fixes the regression introduced

func - pad function,
pull - termination,
rst - pad reset config,
trig - rx level/edge configuration,
bufdis - rx/tx (in/output) buffer disable.
The patch resolves the above problem by adding a new macro for the
