Sparse is not happy about strict type handling:
.../typec/tcpm/tcpm.c:2720:27: warning: restricted __le16 degrades to integer
.../typec/tcpm/tcpm.c:2814:32: warning: restricted __le16 degrades to integer
Fix this by converting LE to CPU before use.
Fixes: ae8a2ca8a221 ("usb: typec: Group all TCPCI/TCPM code together")
Fixes: 64f7c494a3c0 ("typec: tcpm: Add support for sink PPS related messages")
