soc: hisilicon: kunpeng_hccs: replace MAILBOX dependency with PCC

The kunpeng_hccs driver depends on the Platform Communication Channel
Driver. If the PCC driver is not enabled, this driver will be failed
to probe. And since the PCC driver depends on the MAILBOX, replace
the MAILBOX dependency with the PCC.
