we get the device based on its name and in addition by its label.

The tcpc_get_status_register function was using int32_t for the status
parameter, while the other related functions used uint32_t. This change
unifies the data type across all related functions to uint32_t for
consistency and clarity.

To remove CONFIG_PINCTRL from board side for numaker boards.
The Drivers using Pinctrl should be turning Pinctrl on
instead of the responsibility of the board.

This follows update of UTCPD.VBSCALE register field. It supports:
- "divide-20": External VBUS voltage divider circuit should be 1/20
for EPR application. The divided voltage compares with
200mV to set or clean VBUS Present bit.
- "divide-10": External VBUS voltage divider circuit should be 1/10
for SPR application. The divided voltage compares with
400mV to set or clean VBUS Present bit.

Add bool value that stores the CC change information received in
the interrupt of TCPC alert line. In sink role when in disconnected
state, polling the CC lines causes the chip to be awaken from sleep
mode increasing the power usage. When partner is connected, or any
other CC lines change happens, the chip informs about it with alert.
It can be cached and used instead of asking the chip directly.

2. UTCPD is interconnected with Timer-triggered EADC for updating
VBUS/VCONN voltage periodically

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.

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.
