usb: Switch i2c drivers back to use .probe()

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

While touching hd3ss3220.c fix a minor white space issue in the
definition of struct hd3ss3220_driver.

usb: typec: ucsi: stm32g0: Convert to i2c's .probe_new()

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

i2c: Make remove callback return void

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

usb: typec: ucsi: stm32g0: add bootloader support

STM32G0 comes with STM32 bootloader in its system memory. Add support
for some I2C bootloader commands as described in application notes
AN2606 and AN4221, to enable STM32G0 UCSI firmware update.

Upon probing, the driver needs to know the STM32G0 state:
- In bootloader mode, STM32 G0 answers at i2c addr 0x51.
- In running mode, STM32 G0 firmware may answer at two address.
- The main address specified in DT is used for UCSI.
- 0x51 addr can be re-used for FW controls like getting software version
or jump to booloader request.

So probe using the main firmware i2c address first, before attempting
bootloader address (e.g. check for blank, erased or previously aborted
firmware update).

usb: typec: ucsi: stm32g0: add support for stm32g0 controller

STM32G0 provides an integrated USB Type-C and power delivery interface.
It can be programmed with a firmware to handle UCSI protocol over I2C
interface. A GPIO is used as an interrupt line.

Type-C connector can be used as a wakeup source (typically to detect
changes on the port, like attach or detach). PM suspend / resume routines
are used to enable wake irqs, and signal a wakeup event in case the IRQ
has fired while in suspend. The i2c core is doing the necessary
initialization when the "wakeup-source" flag is provided.
Note: the interrupt handler shouldn't be called before the i2c bus resumes.
So, the interrupts are disabled during suspend period, and re-enabled
upon resume, to avoid i2c transfer while suspended, from the irq handler.
