[Xen-devel] [PATCH] xen/arm64: livepatch: Fix build after 03957f58db

[Julien Grall <julien.grall@xxxxxxx>]

Commit 03957f58db "xen/const: Extend the existing macro BIT to take a
suffix in parameter" didn't convert all the callers of the macro BIT.

This will result to a build breakage when enabling Livepatch on arm64.
