Fix mangle bootargs patch compilation warning due to defined but not
used functions.
Fix compilation warning:
arch/arm/boot/compressed/atags_to_fdt.c:63:17: error: 'get_cell_size' defined but not used [-Werror=unused-function]
   63 | static uint32_t get_cell_size(const void *fdt)
      |                 ^~~~~~~~~~~~~

Also make some variable const to fix compilation warning:
arch/arm/boot/compressed/atags_to_fdt.c: In function 'append_rootblock':
arch/arm/boot/compressed/atags_to_fdt.c:91:13: error: assignment discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
   91 |         ptr = str - 1;
      |             ^
