i3c: simplify combined i3c/i2c dependencies

Browse Source 
All combined i2c/i3c drivers appear to suffer from the same link
time problem when CONFIG_I3C is set to 'm':

arm-linux-gnueabi-ld: drivers/iio/magnetometer/mmc5633.o: in function `mmc5633_i3c_driver_init':
mmc5633.c:(.init.text+0x30): undefined reference to `i3c_driver_register_with_owner'

This was previously fixed every time by marking individual
drivers as 'depends on I2C; depends on I3C || !I3C', but this gets
tedious and is somewhat confusing.

Add a Kconfig symbol 'I3C_OR_I2C' to help replace those dependencies,
and use this in all the existing drivers that had already fixed it
as well as the new mmc5633 driver.

Device drivers using module_i3c_i2c_driver() can use either
i2c or i3c hosts, but cannot be built-in for the kernel when
CONFIG_I3C=m.
Add 'depends on I2C_OR_I3C' in Kconfig for those drivers to
get the correct dependencies.
