ARM: fdt: Bump CPU_NAME_MAX_LEN to avoid silly GCC warning
GCC 7 warns about truncating the mpidr when we print the cpu_name into
the device tree:
arm/fdt.c: In function ‘setup_fdt’:
arm/fdt.c:58:45: error: ‘%lx’ directive output may be truncated writing between 1 and 10 bytes into a region of size 7 [-Werror=format-truncation=]
snprintf(cpu_name, CPU_NAME_MAX_LEN, "cpu@%lx", mpidr);
Fix this by bumping the buffer to 15 bytes. We really only need 11 bytes,
but GCC isn't smart enough to identify that we mask out the top buts
of the MPIDR and the analysis just seems to be based on types.
