mb/google/brya: Don't add MPTS to both DSDT and SSDT

commit 52ccd293d7 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.
