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.

Guru Das Srinagesh and Ashay Jaiswal.
