mb/google/brya: Don't add MPTS to both DSDT and SSDT
commit 52ccd293d7 ("mb/google/brya: Implement shutdown function for dGPU") started unconditionally adding MPTS to the SSDT. On variants with HAVE_WWAN_POWER_SEQUENCE selected, MPTS is already added to the DSDT via wwan_power.asl. The duplicate definition results in a kernel error: ERR kernel: [ 0.109237] ACPI BIOS Error (bug): Failure creating named object [\_SB.MPTS], AE_ALREADY_EXISTS (20210730/dswload2-327) ERR kernel: [ 0.109242] ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20210730/psobject-220) Don't add MPTS to the SSDT if HAVE_WWAN_POWER_SEQUENCE is selected. There are no variants which use both, so this should only result in empty MPTS methods being removed. BUG=b:260380268 TEST=On pujjo, the SSDT no longer contains an empty MPTS method, there's no kernel error, and the WWAN power-off sequence is met.
