Subject: [PATCH v3 1/2] pinctrl: nuvoton: npcm7xx: Use %zu printk format for ARRAY_SIZE()

When compile-testing on 64-bit architectures, GCC complains about the
mismatch of types between the %d format specifier and value returned by
ARRAY_LENGTH(). Use %zu, which is correct everywhere.

Reported-by: kernel test robot <lkp@...el.com>
Fixes: 3b588e43ee5c7 ("pinctrl: nuvoton: add NPCM7xx pinctrl and GPIO driver")
Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@....net>
Reviewed-by: Andy Shevchenko <andy.shevchenko@...il.com>

v3:
- Change from %zd to %zu because we're dealing with an unsigned value

v2:
- Add Fixes and R-b tags
