configs: rhel: Fix designware I2C controllers related config settings
Before 6.12 CONFIG_I2C_DESIGNWARE_CORE was not user selectable, instead
it was automatically selected by CONFIG_I2C_DESIGNWARE_PLATFORM /
CONFIG_I2C_DESIGNWARE_PCI.
Commit 9d1fbf22cff7 ("[redhat] New configs in drivers/i2c") created
redhat/configs/rhel/generic/CONFIG_I2C_DESIGNWARE_CORE with
"# CONFIG_I2C_DESIGNWARE_CORE is not set" to deal with it now
being user selectable.
This is causing all the other CONFIG_I2C_DESIGNWARE_* options to be
disabled breaking anything connected to any designware I2C controllers,
such as touchpads, accelerometers, fuel-gauges, USB Type-C controllers,
camera sensors, etc.
This commit changes 3 designware I2C controllers configs to fix things:
1. Change the generic CONFIG_I2C_DESIGNWARE_CORE to 'm' to re-enable
CONFIG_I2C_DESIGNWARE_PLATFORM which is 'm' in RHEL.
2. Many x86 laptops require CONFIG_I2C_DESIGNWARE_PCI for I2C connected
touchscreens and touchpads, set CONFIG_I2C_DESIGNWARE_PCI=m on x86.
3. The designware I2C drivers should not be build on s390x, change
the existing unsetting of CONFIG_I2C_DESIGNWARE_PLATFORM on s390x to
unset CONFIG_I2C_DESIGNWARE_CORE to disable all designware I2C drivers.
