Subject: [PATCH] platform/x86: intel_telemetry: add back linux/io.h inclusion

This one wasn't redundant after all, as shown by this randconfig
build error:

drivers/platform/x86/intel_telemetry_pltdrv.c: In function 'telem_evtlog_read':
drivers/platform/x86/intel_telemetry_pltdrv.c:900:20: error: implicit declaration of function 'readq' [-Werror=implicit-function-declaration]

We should generally include exactly the set of headers that declare
the interfaces we use, so this adds back the missing include to
get it to compile again.

Fixes: a5e50220edbd ("platform/x86: intel_telemetry: cleanup redundant headers")
