WMI drivers using the buffer-based WMI API are expected to reject
undersized query results. Extend wmidev_query_block() to enable
the WMI driver core to perform this size check internally.

Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of
hex.h interfaces to directly #include <linux/hex.h> as part of the process
of putting kernel.h on a diet.
Removing hex.h from kernel.h means that 36K C source files don't have to
pay the price of parsing hex.h for the roughly 120 C source files that
need it.
This change has been build-tested with allmodconfig on most ARCHes. Also,
all users/callers of <linux/hex.h> in the entire source tree have been
updated if needed (if not already #included).

Many older WMI drivers cannot be instantiated multiple times for
two reasons:
- they are using the legacy GUID-based WMI API
- they are singletons (with global state)
Prevent such WMI drivers from binding to WMI devices with a duplicated
GUID, as this would mean that the WMI driver will be instantiated at
least two times (one for the original GUID and one for the duplicated
GUID).
WMI drivers which can be instantiated multiple times can signal this
by setting a flag inside struct wmi_driver.
Tested on a ASUS Prime B650-Plus.
