93e7024e0a usb: typec: Disable async suspend for fusb301 
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.

Invoking fusb301_set_toggle_time() with input parameter same as
current register value to set toggle time shouldn't be treated as
error.

This patch is to change message level from dev_err() to dev_info()
when above situation is met.
