[PATCH 5.11 193/775] media: ipu3-cio2: Build only for x86

From: Greg Kroah-Hartman

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

[ Upstream commit 3ef5e42d281ea108f4ccdca186de4ce20a346326 ]

According to the original code in the driver it was never assumed to work
with big page sizes: unsigned short type followed by PAGE_SHIFT and
PAGE_MASK which may be different on non-x86 architectures.

Recently LKP found an issue on non-x86 architectures due to above
mentioned limitations. Since Sakari acknowledges that it's not really
useful to be able to compile this elsewhere, mark it x86 only.

Fixes: a31d19f88932 ("media: ipu3: allow building it with COMPILE_TEST on non-x86 archs")
