tcpci: Correct USB-C PD PPC config in header file

If the PD chip has built in PPC, TCPCM uses Sink & Src control
functions from TCPCI driver hence changed the USB-C PD PPC config
name in header file from CONFIG_USBC_PPC to CONFIG_USB_PD_PPC.

BUG=none
BRANCH=none
TEST=Able to directly call the tcpci get and set src & sink
     control function for ADL-RVP board file.
