Crypto Soft: Replace howmany with div_round_up

Summary

This PR replaces the non-standard howmany macro with the common div_round_up macro in the cryptosoft implementation. This improves code consistency across the NuttX codebase and enhances maintainability.

Changes

Files Modified

1. crypto/cryptosoft.c
   • Replace howmany macro calls with standard div_round_up macro
   • Improves code consistency with NuttX standards

Technical Details

Macro Replacement:

• The howmany macro is a non-standard implementation for division with rounding up
• div_round_up is the common NuttX standard macro for the same operation
• This change maintains identical functionality while improving consistency

Benefits:

• Aligns with NuttX coding standards
• Reduces use of non-standard macros
• Improves code readability and maintainability
• Facilitates future refactoring and maintenance

Impact

• Consistency: Improves code consistency across the crypto subsystem
• Maintainability: Easier to maintain and understand
• Standards: Follows NuttX standard patterns
• Compatibility: No functional impact; maintains existing behavior

Testing

No functional changes, existing tests continue to pass.
