powercap / RAPL: Floor frequency setting in Atom SoC
CPU Floor frequency is set in BIOS for newer Atom SoCs. This patch handles configuration of floor frequency for different variants of Atom SoCs appropriately and ensures configuration of floor frequency is not done from driver for these newer Atom SoCs. Since address of the register for configuring floor frequency might change for different Atom SoCs, this patch also prevents potential overwriting of wrong registers.
