dongjiuzhu1 c90b64ed8b nshlib/ls_handler: eliminate floating-point operations for human-readable sizes 
Replace floating-point arithmetic with fixed-point integer math to avoid
linking soft-float library (~2-3KB Flash) when displaying human-readable
file sizes (ls -lh command).

Changes:
- Use integer division and modulo to calculate size components
- Calculate decimal part: (remainder * 10) / unit for one decimal place
- Refactor duplicated code: consolidate GB/MB/KB logic into single path
- Remove CONFIG_HAVE_FLOAT dependency

This eliminates calls to __aeabi_f2d, __aeabi_fmul, __aeabi_i2f and other
ARM EABI floating-point helpers, reducing Flash footprint for systems
compiled with -mfloat-abi=soft.
