Subject: [PATCH] lib/bitmap: remove expect_eq_u32_array

expect_eq_u32_array isn't used from commit 3aa56885e516 ("bitmap:
replace bitmap_{from,to}_u32array").
And EXP2_IN_BITS are never used. so better to remove them.

I think better "fix" will be to add test cases.

On the other hand, it's almost 2 years gone since the commit you
mentioned, and nobody used the check_eq_u32_array(). So I think
it's long enough to consider the function useless.

This function is the last example of 2 lengths in input, so I'd
prefer to remove it. However, removing check_eq_u32_array() should
be synchronized with underlying __check_eq_u32_array().

Thanks for elaboration.
No objection from my side!
