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.
