Add the type-c connector and sbu-mux nodes and hook up the usb phy
ports. The db845c can source 5v@1.5A vbus.

TODO: figure out power-roles. In theory db845c is always power source,
it doesn't actually run off vbus. However legacy cables (type-c ->
type-a) will provide vbus regardless, need to ensure that TCPM can
handle this.

pmi8998 doesn't support fast role swap

Various minor improvements and hacking to try and make dwc3 work at all
in gadget mode.

pmi8998 is eager to disable it's legacy cable detection, make sure it's
on and that we handle it properly, otherwise the type-c state machine
gets a bit confused.

The GENMASK() macro causes a compiler error if the lsb and msb are
specified the wrong way around, however the format of regmap fields
means that the mask isn't calculated until runtime. Use the
GENMASK_INPUT_CHECK() macro to catch this for constant reg_fields.

The current method of cat-ing register file dumps the entire
address space. One can use dd command to dump a subrange within
the address space. However one needs to know the string length
of each line which is derived from max address, the character
length of each register entry and the format.

Provide simple means to dump a range by allowing user to specify
the start address and the count of registers. When the data is read
convert the dump address to a starting position in the file. Similarly
if the file offset goes beyond the dump range return 0 to indicate
that the data is already dumped.

Also provide means to write to a register address.

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 6c8cf369 ("usb: typec: Add QCOM PMIC typec detection
driver") can be deleted entirely.
