usb: typec: qcom: Add Qualcomm PMIC Type-C driver

This commit adds a QCOM PMIC TCPM driver with an initial pm8150b
block.

The driver is layered as follows:

qcom_pmic_typec.c : Responsible for registering with TCPM and arbitrates
                    access to the Type-C and PDPHY hardware blocks in one
                    place.  This presents a single TCPM device to device to
                    the Linux TCPM layer.

qcom_pmic_typec_pdphy.c: Responsible for interfacing with the PDPHY hardware and
                         processing power-delivery related calls from TCPM.
                         This hardware binding can be extended to
                         facilitate similar hardware in different PMICs.

qcom_pmic_typec_port.c: Responsible for notifying and processing Type-C
                        related calls from TCPM. Similar to the pdphy this
                        layer can be extended to handle the specifics of
                        different Qualcomm PMIC Type-C port managers.

This code provides all of the same functionality as the existing
qcom typec driver plus power-delivery as well.

As a result commit 6c8cf3695176 ("usb: typec: Add QCOM PMIC typec detection
driver") can be deleted entirely.
