am33xx: don't assume we have a UCLASS_MISC device present

Boot on am33xx without CONFIG_USB will currently fail, as we error-out
of arch_misc_init() if no UCLASS_MISC device is found. This requirement
was introduced in commit 3aec2648698d ("am33xx: board: probe misc
drivers to register musb devices").

Instead, only attempt the UCLASS_MISC init if we would expect the MUSB
TI device to be present. Add a comment to explain why we're doing the
device lookup (which we immediately discard).
