mb/system76/gaze17: 3060: Fix RTD3 configs

The gaze17, like the oryp9, ties all resets for RTD3 to BUF_PLT_RST#
instead of using dedicated lines and ties the enable GPIO to 3.3VS.

Disable RTD3 config for the CPU PCIe RP and disable L23 for the PCH SSD
slot to fix suspend with Western Digital drives.
