atomisp: avoid warning about unused function
The atomisp_mrfld_power() function isn't actually ever called, because
the two call-sites have commented out the use because it breaks on some
platforms. That results in:
drivers/staging/media/atomisp/pci/atomisp_v4l2.c:764:12: warning: ‘atomisp_mrfld_power’ defined but not used [-Wunused-function]
764 | static int atomisp_mrfld_power(struct atomisp_device *isp, bool enable)
| ^~~~~~~~~~~~~~~~~~~
during the build.
Rather than commenting out the use entirely, just disable it
semantically instead (using a "0 &&" construct), leaving the call in
place from a syntax standpoint, and avoiding the warning.
I really don't want my builds to have any warnings that can then hide
real issues.
