[PATCH v4] staging: media: atomisp: fix coding style in ia_css_output.host.c

[LiangCheng Wang <zaq14760@gmail.com>]

Fix multiple checkpatch.pl ERRORs and coding style issues:

- Use tabs instead of spaces for indentation
- Move trailing `if` statements to multiline format
- Remove excessive space between type and asterisk in function
  arguments
- Move assignment operator '=' to the same line for static struct
  definitions
- Remove unnecessary line breaks in function definitions

This cleanup improves code readability and follows Linux kernel
coding standards.
