[PATCH] clk: renesas: rzg2l: Rename iterator in for_each_mod_clock() to avoid shadowing

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Rename the internal loop iterator variable in the for_each_mod_clock()
macro from 'i' to '__i'.

The current naming conflicts with local loop variables named 'i' inside
code blocks that utilize the macro, triggering compiler warnings due to
variable shadowing:

  drivers/clk/renesas/rzg2l-cpg.c:1494:36: warning: declaration of `i` shadows a previous local [-Wshadow]
   1494 |                  for (unsigned int i = 0; i < clk->num_shared_mstop_clks; i++)

Using a unique identifier for the macro-internal iterator resolves the
shadowing warnings globally across all macro expansions.

Fixes: 3fd4a8bb4b63 ("clk: renesas: rzg2l: Add macro to loop through module clocks")
