as an eSPI master.
The eSPI baud rate generator clock source (either system clock or system clock divided by 16,
depending on DIV16 bit) is divided by 2* ([PM] + 1), a range from 2 to 32. For example, if the prescale
modulus is set to PM=0x0011 and DIV16 is set, the SPI_CLK/system clock rate will be
16*(2*(0x0011+1))=128
cycle is (PM+1)/(2*PM+1) for DIV16=0; duty cycle is 50% for DIV16=1
