power: sequencing: pcie-m2: Report power controllability
The M.2 Key E connector gates/resets its functions through the
W_DISABLE1# (PCIe/WiFi) and W_DISABLE2# (Bluetooth) signals.
When a signal is not routed to a host GPIO, the corresponding
enable/disable callbacks are no-ops, so the consumer cannot gate
or reset that function on its own.
Implement the .is_controllable() callback on the "uart" and "pcie"
targets so that consumers can query this per instance (based on the
runtime presence of the W_DISABLE2#/W_DISABLE1# GPIOs) via
pwrseq_is_controllable().
