Corrected various spelling mistakes and typos in multiple files under the Xe directory. These fixes improve clarity and maintain consistency in documentation. v2 - Replaced all instances of "XE" with "Xe" where it referred to the driver name - of -> for - Typical -> Typically v3 - Revert "Xe" to "XE" for macro prefix reference Signed-off-by: Sanjay Yadav <sanjay.kumar.yadav@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Reviewed-by: Stuart Summers <stuart.summers@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Link: https://patch.msgid.link/20251023121453.1182035-2-sanjay.kumar.yadav@intel.com
