regmap: fix kcalloc() arguments order

Browse Source 
When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed a bunch of four similar warnings like:

drivers/base/regmap/regmap-ram.c: In function '__regmap_init_ram':
drivers/base/regmap/regmap-ram.c:68:37: warning: 'kcalloc' sizes specified with
'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
   68 |         data->read = kcalloc(sizeof(bool), config->max_register + 1,
      |                                     ^~~~

Since 'n' and 'size' arguments of 'kcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.
