Subject: [PATCH AUTOSEL 5.10 036/137] clk: renesas: r8a77995: Add ZA2 clock

From: Kuninori Morimoto <kuninori.morimoto.gx@...esas.com>

[ Upstream commit 790c06cc5df263cdaff748670cc65958c81b0951 ]

R-Car D3 ZA2 clock is from PLL0D3 or S0,
and it can be controlled by ZA2CKCR.
It is needed for R-Car Sound, but is not used so far.
Using default settings is very enough at this point.
This patch adds it by DEF_FIXED().
