[PATCH] staging/typec: fix tcpci_rt1711h build errors

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix Kconfig warning and build errors in staging/typec/rt1711h.c.
The driver uses I2C interfaces so it should depend on I2C.

WARNING: unmet direct dependencies detected for TYPEC_TCPCI
  Depends on [m]: STAGING [=y] && TYPEC_TCPM [=y] && I2C [=m]
  Selected by [y]:
  - TYPEC_RT1711H [=y] && STAGING [=y] && TYPEC_TCPM [=y]
