From: Pali Rohár <pali@xxxxxxxxxx> commit 1fb95d7d3c7a926b002fe8a6bd27a1cb428b46dc upstream. There are lot of undocumented interrupt bits. To prevent unwanted spurious interrupts, fix all *_ALL_MASK macros to define all interrupt bits, so that driver can properly mask all interrupts, including those which are undocumented.
