Chester Lin 08e8734d87 pinctrl: s32cc: Avoid possible string truncation
With "W=1" and "-Wformat-truncation" build options, the kernel test robot
found a possible string truncation warning in pinctrl-s32cc.c, which uses
an 8-byte char array to hold a memory region name "map%u". Since the
maximum number of digits that a u32 value can present is 10, and the "map"
string occupies 3 bytes with a termination '\0', which means the rest 4
bytes cannot fully present the integer "X" that exceeds 4 digits.

Here we check if the number >= 10000, which is the lowest value that
contains more than 4 digits.
