[PATCH] clk: renesas: r8a7799[05]: Add MLP clocks

[Nikita Yushchenko]

Add clocks for MLP modules on Renesas R-Car E3 and D3 SoCs.

Similar to other R-Car Gen3 SoC, exact information on parent for MLP
clock on E3 and D3 is not available. However, since parent for this
clocl is not anyhow software-controllable, the only harm from this
is inexact information exported via debugfs. So just keep the parent
set in the same way as with other Gen3 SoCs.

i.e. will queue in renesas-clk-for-v5.18, with the typos fixed.
