    oxnas: 5.15: fix mangle bootargs patch compilation warning
    
    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)
          |                 ^~~~~~~~~~~~~
    arch/arm/boot/compressed/atags_to_fdt.c:43:12: error: 'setprop_cell' defined but not used [-Werror=unused-function]
       43 | static int setprop_cell(void *fdt, const char *node_path,
          |            ^~~~~~~~~~~~
    arch/arm/boot/compressed/atags_to_fdt.c:25:12: error: 'setprop' defined but not used [-Werror=unused-function]
       25 | static int setprop(void *fdt, const char *node_path, const char *property,
          |            ^~~~~~~
    arch/arm/boot/compressed/atags_to_fdt.c: In function 'atags_to_fdt':
    arch/arm/boot/compressed/atags_to_fdt.c:207:18: error: unused variable 'memsize' [-Werror=unused-variable]
      207 |         int ret, memsize;
          |                  ^~~~~~~
    arch/arm/boot/compressed/atags_to_fdt.c:206:13: error: unused variable 'memcount' [-Werror=unused-variable]
      206 |         int memcount = 0;
          |             ^~~~~~~~
    arch/arm/boot/compressed/atags_to_fdt.c:205:16: error: unused variable 'mem_reg_property' [-Werror=unused-variable]
      205 |         __be32 mem_reg_property[2 * 2 * NR_BANKS];
          |                ^~~~~~~~~~~~~~~~
    arch/arm/boot/compressed/atags_to_fdt.c: At top level:
    arch/arm/boot/compressed/atags_to_fdt.c:174:13: error: 'hex_str' defined but not used [-Werror=unused-function]
      174 | static void hex_str(char *out, uint32_t value)
          |             ^~~~~~~
    cc1: all warnings being treated as errors
    
    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;
          |             ^
