    generic: routerbootpart: fix compilation on 64-bit
    
    Trying to compile routerbootpart parsers on 64-bit platforms will fail:
    drivers/mtd/parsers/routerbootpart.c: In function 'routerboot_find_dynparts':
    ./include/linux/kern_levels.h:5:25: error: format '%X' expects argument of type 'unsigned int', but argument 3 has type 'size_t' {aka 'long unsigned int'} [-Werror=format=]
        5 | #define KERN_SOH        "\001"          /* ASCII Start Of Header */
          |                         ^~~~~~

          |         ^~~~~~
    ./include/linux/kern_levels.h:11:25: note: in expansion of macro 'KERN_SOH'
       11 | #define KERN_ERR        KERN_SOH "3"    /* error conditions */
          |                         ^~~~~~~~
    ./include/linux/printk.h:498:16: note: in expansion of macro 'KERN_ERR'
      498 |         printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__)
          |                ^~~~~~~~
    drivers/mtd/parsers/routerbootpart.c:170:25: note: in expansion of macro 'pr_err'
      170 |                         pr_err("%s: mtd_read error while parsing (offset: 0x%X): %d\n",
    
    So, lets simply add the length modifier 'z' to fix compilation.
