usb: typec: Disable async suspend for fusb301

Browse Source 
Upstream commit aa7a9275ab81 ("PM: sleep: Suspend async parents after
suspending children") triggers a suspend issue on Tegra234 Jetson
Orin Nano boards because it had reordered the suspend of devices with
async suspend enabled with respect to some other devices. This commit
is present in Linux v6.16 kernels.

The same issue was observed with the cypd4226 Type-C controller used on
other Jetson platforms and due to its dependencies on other devices it
is necessary to disable async suspend to fix the issue [0]. Fix suspend
for Tegra234 Jetson Nano platforms by disabling 'async' suspend for the
fusb301 device. Note that it is safe to disable this for all kernel
versions.
