Subject: [RFC v1 04/12] checkpatch: add support for struct MOCK(foo) syntax

From: Brendan Higgins <brendanhiggins@...gle.com>

KUnit will soon add macros for generating mocks from types, the
generated mock types are named like `struct MOCK(foo)` (where the base
type is struct foo).

Add `struct MOCK(foo)` as a NonptrType so that it is recognized
correctly in declarations.
