[PATCH 2/2] staging: media: atomisp: Mark pad_w and pad_h as const constants

[Prajval Chaudhary <prajvalchaudhari733@gmail.com>]

Now that the user-facing module parameters for pad_w and pad_h
have been removed, these variables are strictly internal driver
configurations. Mark them as const to prevent accidental runtime
modification and allow compiler optimization.

This completes the internal cleanup follow-up resulting from
addressing the driver's module parameter TODO item.
