Subject: [PATCH] cpufreq: spear: Fix uninitialized variable "i"

The refactoring in commit dca2ef2b7d91 ("cpufreq: spear: Use
of_property_for_each_u32() instead of open coding") left "i"
uninitialized. Initialize it to 0.

Note that gcc doesn't detect this, only clang does.

Fixes: dca2ef2b7d91 ("cpufreq: spear: Use of_property_for_each_u32() instead of open coding")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202408030418.gnJDcCpm-lkp@intel.com/
