Subject: [PATCH v2] clk: renesas: r9a09g047: Add GPT clocks and resets

From: Biju Das <biju.das.jz@...renesas.com>

Add clock and reset entries for the Renesas RZ/G3E GPT{0,1} IPs.

Signed-off-by: Biju Das <biju.das.jz@...renesas.com>
---
v1->v2:
 * Dropped the series as according to the clock system diagram and clock
   list sheets, gpt_[01]_pclk_sfr and gpt_[01]_clks_gpt are really the
   same clocks.
 * Dropped R9A09G047_GPT_1_CLKS_GPT macro
 * Replaced DEF_MOD_PARENT->DEF_MOD for module clks.
