soc/intel/common: Calculate and configure SF Mask 2
As per TGL EDS, two ways will be controlled with one bit of SF QoS
register hence, this patch introduces SF_MASK_2WAYS_PER_BIT Kconfig to
allow SoC users to select SF_MASK_2WAYS_PER_BIT to follow the EDS
recommendation.
Calculate SF masks 2:
1. if CONFIG_SF_MASK_2WAYS_PER_BIT:
a. data_ways = data_ways / 2
Also, program SF Mask#2 using below logic:
2. Set SF_MASK_2 = (1 << data_ways) - 1
