x86/platform/intel/iosf: Add better description of IOSF driver in config

Adds better description of IOSF driver to determine when it
should be enabled. Also moves the Kconfig option to "Processor
type and features" menu from main configuration menu.

+         This option enables sideband register access support for Intel SoC
+         platforms. On these platforms the IOSF sideband is used in lieu of

+         and power. Drivers may query the availability of this device to
+         determine if they need the sideband in order to work on these
