PCI: sg2042: Avoid L0s and L1 on Sophgo 2042 PCIe Root Ports

Since commit f3ac2ff14834 ("PCI/ASPM: Enable all ClockPM and ASPM states
for devicetree platforms") force enables ASPM on all device tree platforms,
the SG2042 Root Ports are breaking as they advertise L0s and L1
capabilities without supporting them.

Set ASPM quirks to disable the L0s and L1 capabilities for the Root Ports
so that these broken link states won't be enabled.

Fixes: 4e27aca4881a ("riscv: sophgo: dts: add PCIe controllers for SG2042")
