thinkpad-acpi: improve Kconfig help text

Document that rfkill and ALSA functionality exists, but requires the
subsystems to be available, and not modular if thinkpad-acpi is not
modular.

This driver was formerly known as ibm-acpi.
Extra functionality will be available if the rfkill (CONFIG_RFKILL)
and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
Note that if you want ThinkPad-ACPI to be built-in instead of
modular, ALSA and rfkill will also have to be built-in.
If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
