These nodes are required for USB C, which the Turing RK1 does not have.

Ignore this pr. The pins on the SoM used for USB C are connected to the USB 2.0 OTG port. |

The following bug was triggered on a system built with CONFIG_DEBUG_PREEMPT=y: # echo p > /proc/sysrq-trigger BUG: using smp_processor_id() in preemptible [00000000] code: sh/117 caller is perf_event_print_debug+0x1a/0x4c0 CPU: 3 UID: 0 PID: 117 Comm: sh Not tainted 6.11.0-rc1 armbian#109 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x4f/0x60 check_preemption_disabled+0xc8/0xd0 perf_event_print_debug+0x1a/0x4c0 __handle_sysrq+0x140/0x180 write_sysrq_trigger+0x61/0x70 proc_reg_write+0x4e/0x70 vfs_write+0xd0/0x430 ? handle_mm_fault+0xc8/0x240 ksys_write+0x9c/0xd0 do_syscall_64+0x96/0x190 entry_SYSCALL_64_after_hwframe+0x4b/0x53 This is because the commit d4b294b ("perf/x86: Hybrid PMU support for counters") took smp_processor_id() outside the irq critical section. If a preemption occurs in perf_event_print_debug() and the task is migrated to another cpu, we may get incorrect pmu debug information. Move smp_processor_id() back inside the irq critical section to fix this issue.

These nodes are required for USB C, which the Turing RK1 does not have. So they should be removed.
Thanks!
