Since all UCPD devices share the same ISR, the interrupt
should be enabled after all UCPD devices are initialized.

At system startup, the SYSCFG ITLINE registers might not
indicate an interrupt even though a UCPD interrupt is pending.
This cause the ISR to be called repeatedly without being serviced,
resulting in a system lockup. Reading the UCPD Status Reg instead
of the SYSCFG ITLINE register fixes the issue.

Update TCPC driver to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.

The "@return" command should be used for the arbitrary return
description, and "@retval <return value>" for the description
of named return value

Use DT_NUM_INST_STATUS_OKAY(DT_DRV_COMPAT) to determine
number of potential interrupt sources. This mitigates
the wasting of memory on devices with mutliple UCPD ports
but only one UCPD port is used.

Assign the pins for the STM32G071b and STM32G081b STM32
UCPD peripherals so the UCPD driver can properly
configure the device.
