usb: typec: qcom-pmic-typec: add support for PMI632 PMIC

The PMI632 PMIC support Type-C port handling, but lacks USB
PowerDelivery support. The TCPM requires all callbacks to be provided
by the implementation. Implement a special, 'stub' Qcom PD PHY
implementation to enable the PMI632 support.

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.
