board: rock5b-rk3588: enable USB-C in operating system

Since older U-Boot releases do not negotiate USB PD, the kernel
DT may not enable the USB-C controller by default to avoid a
regression. The plan is to upstream it with 'status = "fail";'
instead. U-Boot should then mark it as 'status = "okay";' if
it negotiated USB PD. Currently existing upstream kernel DTs do
not yet have the USB-C controller at all, so we ignore any
failures.
