As noted in PR#63165 checking of result should use comparison to
success value instead of checking if result is negative. It will
allow to check if function returned invalid but positive value.

These two functions are used together so there is no need for
splitting them into two functions. This commit also makes this
function required to be implemented by the TCPC driver.

TCPC API functions should be able to inform the caller if the function
is supported and successfully executed. Bool values doesn't allow this
so it is needed to change the type to int.
For is_rx_pending_msg function the return code should conform to
existing error codes, so in case of function being not supported,
the -ENOSYS should be returned. In case of successful execution,
if there is no pending message, the -ENODATA should be returned and
in case of message pending, the value of 0.

There was a new Kconfig for USB-C init priority that is conflicting
with currently used Kconfig for init of VBUS and TCPC.
This commit changes the names to more specific related to the subsystem
they belong to.

The Dead Battery resistors interfere with port partner
detection. So, Dead Battery is disabled after the system
starts and sets the Rd or Rp resistors on the CC lines.
Tested on b_g474e_dpow1 with JP5 set to USBC.
Tested on stm32g081b_eval with JP17 set to D5V.

This change enables the ISR Hard Reset sent bits, so that
an interrupt is generated when a Hard Reset is sent or
the Hard Reset failed.

The Hard Reset sent signal was tested twice in the same
"if else" structure but only handled in the last test. This
change removes the first detection so that Hard Reset can
be correctly detected.

When operating as a Source, the driver will wait indefinitely for
a GoodCRC message from a Sink. This PR adds a timer to trigger a
no response when a GoodCRC message isn't received.

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.

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.
