HID: intel-ish-hid: fix module device-id handling
A late addititon to the intel-ish-hid framework caused a build failure
with clang, and introduced an ABI to the module loader that stops working
if any driver ever needs to bind to more than one UUID:
drivers/hid/intel-ish-hid/ishtp-fw-loader.c:1067:4: error: initializer element is not a compile-time constant
Change the ishtp_device_id to have correct documentation and a driver_data
field like all the other ones, and change the drivers to use the ID table
as the primary identification in a way that works with all compilers
and avoids duplciating the identifiers.
Fixes: f155dfeaa4ee ("platform/x86: isthp_eclite: only load for matching devices")
Fixes: facfe0a4fdce ("platform/chrome: chros_ec_ishtp: only load for matching devices")
