Subject: accel/habanalabs: Don't build the driver on UML
X-Git-Tag: block-6.16-20250606~23^2~25^2

accel/habanalabs: Don't build the driver on UML

The following commit:

  288a4ff0ad29 ("x86/msr: Move rdtsc{,_ordered}() to <asm/tsc.h>")

removed the <asm/msr.h> include from the accel/habanalabs driver, which broke
the build on UML:

   drivers/accel/habanalabs/common/habanalabs_ioctl.c:326:23: error: call to undeclared function 'rdtsc'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

Make the driver depend on 'X86 && X86_64', instead of just 'X86_64',
thus it won't be built on UML.
