Currently, we step into drivers/hid/ based on the value of
CONFIG_HID.
However, that value is a tristate, meaning that it can be a module.
As per the documentation, if we jump into the subdirectory by
following an obj-m, we can not compile anything inside that
subdirectory in vmlinux. It is considered as a bug.
To make things more friendly to HID-BPF, split HID (the HID core
parameter) from HID_SUPPORT (do we want any kind of HID support in the
system?), and make this new config a boolean.

AMD SFH (Sensor Fusion Hub) is a solution running on MP2
(which is ARM core connected to x86 for processing sensor data).
AMD SFH uses HID over PCI bus to form the HID descriptors and
talks to HID clients like the monitor-sensor/iio-proxy. MP2 which
is exposed as a PCI device to the x86, uses mailboxes to talk to
MP2 firmware to send/receive commands.
