cmd: avb: Fix compiler warnings

When building U-Boot with AVB enabled, compiler shows next warnings:

    cmd/avb.c: In function 'do_avb_read_pvalue':
    cmd/avb.c:371:18: warning: format '%ld' expects argument of type
                      'long int', but argument 2 has type 'size_t'
                      {aka 'unsigned int'} [-Wformat=]
       printf("Read %ld bytes, value = %s\n", bytes_read,
                    ~~^                       ~~~~~~~~~~
                    %d

    cmd/avb.c: In function 'do_avb_write_pvalue':
    cmd/avb.c:404:19: warning: format '%ld' expects argument of type
                      'long int', but argument 2 has type '__kernel_size_t'
                      {aka 'unsigned int'} [-Wformat=]
       printf("Wrote %ld bytes\n", strlen(value) + 1);
                     ~~^           ~~~~~~~~~~~~~~~~~
                     %d

Fix those by using "%zu" specified.
