{sb,soc}/amd/cmn/acpi/sleepstates.asl: Hook up configs
Commit cbc5d3f34b87db779829eabc90c32780a3865a56 ("soc/intel: Don't report _S1 state when unsupported") added the `ACPI_S1_NOT_SUPPORTED` option and commit 0eb5974def63a2fc0dce6dfdad62b0b4c6f4b865 ("acpigen: Add a runtime method to override exposed _Sx sleep states") added a mechanism to override the enabled sleep states at runtime. However, these were only hooked up to Intel sleepstates. so the options would not have any effect on AMD platforms. Apply the changes from these two commits to AMD sleepstates so that both options can be used on AMD platforms as well.
