[PATCH v2 02/12] media: atomisp: simplify sh_css_defs.h

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

There are several unused macros. Simplify the logic there, making
it closer to the Intel Aero driver and the corresponding firmware,
as this is what we have widely available for this device.
