Subject: [PATCH V6 02/21] platform/surface: Disable for RISC-V

With CONFIG_ACPI enabled for RISC-V, this driver gets enabled
in allmodconfig build. However, RISC-V doesn't support sub-word
atomics which is used by this driver and hence allmodconfig
build will fail.

There is currently no plan to support this driver for RISC-V. So,
disable this driver for RISC-V even when ACPI is enabled.
